1: No spam or advertising. This basically means no linking to your own content on blogs, YouTube, Twitch, etc.
2: No bigotry or gatekeeping. This should be obvious, but neither of those things will be tolerated. This goes for linked content too; if the site has some heavy "anti-woke" energy, you probably shouldn't be posting it here.
3: No untagged game spoilers. If the game was recently released or not released at all yet, use the Spoiler tag (the little ⚠️ button) in the body text, and avoid typing spoilers in the title. It should also be avoided to openly talk about major story spoilers, even in old games.
Achievement Hunter is what made me wonder. I knew they used Java for Galacticraft but I thought they used Bedrock for pretty much everything else.
I also don't know how popular streaming Bedrock multiplayer servers is. I think they are called Realms.
The service for JE is called Realms and for Bedrock it's Realms Plus. Certain server side mods aren't possible on bedrock.
