What belongs here
Stay inside the room’s stated scope rather than adjacent fandoms or general off-topic dumps. Self-promotion and advertising are tightly limited—read those rules before linking your own channel, shop, or site. Civility and anti-harassment rules are explicit; personal attacks get you removed regardless of how right you think you are.
How it differs from lookalikes
The length of the public rule list is itself a signal: skim all of them once before assuming defaults from similar communities.
Practical pointers
Read the current sidebar/rules on Reddit before posting; collected rules can lag. Avoid clickbait titles; say what the post actually is.
