- People putting periods at the end of goddamn thread titles. It's a title. Not your damn post.
- As others mentioned, we don't need a "we need to talk about..." no
- Bringing ones avatar into the discussion as if it matters
- Constant negativity on a lot things where there's some normal positivity
- drive-by posts which tie into the previous pet peeve
- Not transparent enough reasons to lock a thread by staff. I don't think it hurts to be specific and explain your judgement, this is no different from that Modbot.
