For other members, we can report such posts as spam.
If such posts are from participants of the famed scam site - 1xbit, I think it's pointless wasting efforts in reporting them. Those who are enrolled there and the project they promote deserve each other.

Manager (and forum users) can only see edited if they visit a specific topic to see that post. If the manager only count posts in post history of a participant, it is impossible to know that post was edited or not.
Oh, really? Then that could be a major reason I shockingly find shitposters in some reputable campaigns. Reading isolated posts without following the stream of thought in the thread is likely not going to expose even off topic posts, the same way it won't expose edited posts too. It should behoove managers to do thorough jobs and monitor what their participants post. After all, they say that what is worth doing at all should be worth doing well.
