Most data shown so far looked at the Peak per Minute numbers, so I wanted to see the day data instead.
I took the data from the blackout.photon-reddit site source.
It seems that it makes a Reddit Api call every Minute searching the newest Post and Comment and calculates both per Minute rates.
I wanted to see the effect the Blackout had over the day, so I summed the data and plotted it. Seems like between 11th and 12th June the comments/day diminished by -19.2%. The posts/day saw a decline of -8.9%.
I have also been looking at the Subreddit Stats: Most comments and posts come from r/Askreddit. On 13th June the Sub had 2.4% of the total comments and 0.44% of the total site posts. Sadly I can't see the list of the most commenting and posting subs from reddit before the Blackout because it doesn't seem to work on wayback machine.
But currently it seems like the Top100 commenting Subreddits only make out ~10% (Askreddit: ~1.5%) . So the bulk of the comments happens on the sheer number of other active subreddits.
The subreddit stats site also doesn't show how it gets the data and doesn't make it easy to see historical data overview. During the Blackout there seems to have been post spamming from a now banned german nsfw sub that had even more posts/day than Askreddit
yeah you can't distinguish between bots and humans. But like said in the post, currently the top100 commenting subs only take part in ~10% of the total comments. This would fit with the dead internet theory imo.
But it is also important to note that for this info the comments/day numbers come from two different sources, so it is hard to verify the validity.
The comment numbers of the top100 subreddits are from subredditstats.com, while the total is from the script used by blackout.photon-reddit.com
For subredditstats.com there is no way to see how the data is obtained/tracked.
But the blackout.photon site has its source code available. I just have not enough programming experience to tell if the comments/min number is obtained by a direct api call, or if it calculates the comment ID Delta between each call that it does (it calls the most recent comment each minute).
