Expanded one of the FAQ questions:
When it comes to accusations of commercial misconduct, if a user is accusing you / someone else of scamming or defrauding them in your / someone else's sales thread without providing evidence (either in the post itself or by linking to evidence elsewhere), that's considered low value and thus should be reported as such.
I was just about to update local thread with this, but I don't understand something:
Does this new rule apply to users who wrongly accuse other users of being a gang, mafia, criminals without any single proof or it is just for someone who accuse "seller" without proof?
AFAIK this only applies to sales threads (threads where a user is asking for or offering services and / or goods). Obviously, pure "scam" or "you are a criminal" posts were already considered low value since beyond a vague accusation they neither contain evidence nor any explanation / elaboration on that statement. Whether the "evidence or GTFO" interpretation of the low value post rule is site wide, is something you're going to have to ask theymos.
