Moderator Guidelines
Moderator Guidelines
- Don’t be mean to users. Be gentle or neutral.
- Most moderator actions which have a modlog message should include your username.
- When in doubt about whether or not a user is problematic, send them a DM.
- Don’t waste time debating/arguing with problematic users.
- Assume the best, but don’t tolerate sealioning/just asking questions/concern trolling.
- Ask another mod to take over cases you struggle with, if you get tired, or when things get personal.
- Ask the other mods for advice when things get complicated.
- Share everything you do in the mod matrix, both so several mods aren't unknowingly handling the same issues, but also so you can receive feedback on what you intend to do.
- Don't rush mod actions. If a case doesn't need to be handled right away, consider taking a short break before getting to it. This is to say, cool down and make room for feedback.
- Don’t perform too much moderation in the comments, except if you want a verdict to be public or to ask people to dial a convo down/stop. Single comment warnings are okay.
- Send users concise DMs about verdicts about them, such as bans etc, except in cases where it is clear we don’t want them at all, such as obvious transphobes. No need to notify someone they haven’t been banned of course.
- Explain to a user why their behavior is problematic and how it is distressing others rather than engage with whatever they are saying. Ask them to avoid this in the future and send them packing if they do not comply.
- First warn users, then temp ban them, then finally perma ban them when they break the rules or act inappropriately. Skip steps if necessary.
- Use neutral statements like “this statement can be considered transphobic” rather than “you are being transphobic”.
- No large decisions or actions without community input (polls or meta posts f.ex.).
- Large internal decisions (such as ousting a mod) might require a vote, needing more than 50% of the votes to pass. Also consider asking the community for feedback.
- Remember you are a voluntary moderator. You don’t get paid. Take a break when you need one. Perhaps ask another moderator to step in if necessary.

Why are you still burning CDs?
Why do people buy vinyl?
Because of the fidelity, that’s not a thing with burnt discs..
That's categorically false. And ultimately, fidelity to what? Modern records are analog pressings of almost always digitally recorded, digitally mixed works. What is the record doing that's more "faithful" than, say, the original digital master copy?
Yes because your BURNT cd hasn’t had a few steps to degrade the quality… a bought cd would be better than a BURNT cd.
That doesn't really address the point here. People buy modern vinyl, which is generally several steps from original recordings/mixes as well. It's literally the same issue. You can always say "it needs to be more faithful," but faithful to what?
People don't buy records because they're "objectively better" or "more faithful" or whatever terminology we want to use. There are several possible reasons, usually revolving around the physical format itself/the experience and ritual, as well as the tonal hallmarks of lacquer. If you want "fidelity" outside of "simulates what people were listening to upon release," [edit] most consumer vinyl records are not a good medium. Which is why people buy them - like CD's - for various reason.
A burned CD can achieve a lot of different aims, just like a record can. You should actually talk to people in the hobby to inform yourself here.
A BURNT cd isn’t lossless so that’s just plain false mate….
Bloviate about whatever, but dude asked about burning a cd, you made a comment about vinyl which can be lossless, while a BURNT cd never will. A bought cd yes, as I did already clarify.
Wouldn't that statement depends on various factors?
Was the master digital?
Was the CD ripped at 44,1 kHz and 16-bit resolution?
Was the CD burnt according to the same parameters?
If all of those are true, then one could say that the burnt CD is lossless.
you keep making up standards and strawman here to make your point. Do what you want man, I’m out.
Making up “Standards”? It’s a principle of burning discs, it’s not lossless like you are falsely claiming it is.
Vinyl has more fidelity than a BURNT disc, even if you got a hold of the master recording and burnt it your self. It will not be a lossless transfer. Unlike bought cds and vinyl.
*new vinyl.
Since playing vinyls isn't lossless.
Neither is playing a disc. A vinyl has more fidelity than a burnt disc with crappy lossy files. I thought a topic about burning people would understand the basics of file transfers loss, downloading loss, and burning losses. But clearly some people just want to insult people, I thought buddy was asking g a legit question, turned out they wanted to insult someone while not even understanding the basics of the topic at hand.
Does the laser damage the CD?
👍
A CD, burned or pressed, will be a replication of the source as presented in a digital format. If you have to covert true analog sound to digital then the sampling rate will have some technical loss, though not perceivable to most humans.
A digital to digital copy will be a 1 to 1 replication of the data, there's no expectation of loss other than perhaps physical error of the drive, which even pressed disks can suffer from if the stamper is worn.
Edit Source: literally worked in a optical media replication plant back when DVD was still a fairly new thing. It starts off making a glass master disk in a clean room. From that, a positive metal stamper plate is created for production runs, tested periodically to verify the output still matches the master dataset. Once the metal stamper is worn to the point of causing errors it is replaced.
Burned disks are functionally identical to pressed disks in operation but work by darkening bits in the media layer. They degrade easier because of the photo sensitivity needed to let the laser change their state.
You are mostly right, except this line. And I think I understand your meaning but I think it's a little misleading.
A digital to digital copy can be a 1:1 replication. But just saying "digital to digital" doesn't mean the copy process is lossless, there are a ton of lossy transfer methods. I don't believe they are used when burning CDs (honestly not sure, but I googled it real quick) but just because it's digital doesn't mean it can't have losses
Assuming there's no conversion I might have added in. Yes if you change from wav to mp3 or similar there will be changes. A disk image copy, or even placing a digital file onto a disk doesn't alter the content regardless of burned or pressed, only the method of storage. A hash of the file should return the same regardless assuming no errors in the writing.
Every file transfer creates some noise and loss to the file. Unless you’re using high quality Flac files, which not everyone burning and downloading files are doing so, or it’s already been converted or transferred and incurred corruption.
If you transfer an mp3 1000 times, it’s gonna degrade. You can’t use hashes to fill in missing audio portions like you can with text or something.
Every time you transfer a file, there is loss, this isn’t unique to audio files. Your entire comment is wrong. Even downloading a file online won’t create a perfect copy of the audio file because of data loss, even with hashes.
That's not the case. We can copy a music CD in a lossless way, losing no information.
Burning low bitrate mp3s will obviously be worse.
And the music they ripped is what quality…? When you start off without the master files, you’re already at a loss compared to the originals.
Ripping a bought cd even with”lossless” methods, won’t beat the original printing. That’s just pure fantasy.
Does it matter for on transfer? Unlikely, but how about what someone did before you downloaded the torrent as well?
The fidelity of vinyl, is more than a burnt disc. I didn’t think that was an arguable fact.
We can definitely argue this. A .wav (or a .flac) rip of a track is literally a bit for bit copy, indistinguishable. Look up lossless vs. lossy encoding.
As for vinyl, that's more up to taste. The mastering process can be different for a vinyl pressing as you need to worry about the tracking of the needle. That may be what you like.
You’ve ripped an already degrading file from a cd, it’s already lower quality. You’re arguing that a lossy transfer somehow isn’t lossy…? That’s your argument?
You need to HAVE the original file, or it’s already not lossless. So when burning cds, there’s already an inherent degrading compared to the original master.
How are you getting this already perfect file? This seems to be the part people are ignoring. Sure if you have the master, and burned it yourself, it could be the same fidelity as a vinyl. But this situation is never happening unless you have a contact in the recording industry.
In almost every case, unless you ignore reality, a burnt CD will never the same fidelity…. Since you aren’t dealing with the original file in every case.
Ignore the burning part for a moment, you're telling me a .wav file is lower quality than listening on the CD?
It's a lossless file type.
Edit: if I'm wrong can you explain how?
Not the one you are arguing with, but at which sampling rate and resolution did you rip your CD(44,1 kHz and 16 bit)? Just because it's a WAV files doesn't mean it's a one to one copy.
Okay fair point, but if you rip at 44.1 kHz and 16 bit audio is it not the same file?
Edit: and either way, wouldn't it still be lossless.
There's a technical loss going from an analog to digital format just because of the fact that it's a sampling of the sound wave. Similar to why Pi has no end and you could never calculate the exact measure of a circle, it can get as close as necessary for human consumption, but will never be the pure wave form. Thing is that even an analog format like vinyl isn't a guaranteed perfect recreation just because of micro changes created any number of things that could cause a cutting head to be just a fraction out of line with the original.
What's absurd about the whole argument is this notion that if you take a bit perfect copy of something and duplicate it that somehow inherently something is lost. Somewhat interesting way to consider it, we as living beings do that whole code duplication thing countless times a day just by cellular division as part of living, and for the most part it works without a hitch even without the error correcting code that computer systems have. With digital replication at least it's simple enough to say that sequence A equals sequence B, therefore they are identical.
