A short while ago I've reported (as I can only moderate the altcoin forums and sitewide newbie posts) quite a few low/zero quality, off-topic or trolling posts. I guess either the board moderator, one of the global moderators or one of the administrators handled the reports and deleted said posts.
Here's a few rules they broke from my stickied thread, here in Meta (
https://bitcointalksearch.org/topic/unofficial-list-of-official-bitcointalkorg-rules-guidelines-faq-703657):
1. No zero or low value, pointless or uninteresting posts or threads. [1][e]
2. No off-topic posts.
3. No trolling.
Examples:
1. Such posts like "SELL SELL SELL", "I agree", "+1", "Support", "Watching", "Interesting", "LOL", "SCAM", "LEGIT", "FAKE", other one word posts, posts consisting mostly of swearing, quote pyramids,useless introduction threads, threads about a topic already recently discussed in several other threads.
Complaining, praising or discussing about moderation in the original topic is also considered off-topic.
EDIT: Also, Bitcoin Forum is a fake user set up by theymos (with the intention) to prevent moderator harassment when they delete posts. In my case, that rarely happens as it's almost always obvious who deleted what in the altcoin sections.
