What belongs here
Stay inside the room’s stated scope rather than adjacent off-topic dumps. Low-effort memes/empty shitposts are often removed—add real context.
How it differs from lookalikes
Prefer this room when your post matches its description and rule list—not merely a larger sibling community. The public rule list is long enough that skimming all entries once beats assuming defaults from similar subs.
Practical pointers
Read the live sidebar/rules before posting; collected snapshots can lag. Search before reposting common clips/questions. Avoid clickbait titles.
