Following discussions on Bitcointalk is no fun anymore. There are so many users who post content that have nothing to do with the topic.
Its better to report such "offtopic" posts for the sake of the forum. However mods are already having hands full to clean up the diarrhoea shitposts ejected by self-righteous shitposters and hence its of low value. But still reporting works.

Most of them are member level and lower and are being in a signature campaign. It's obvious that it's spam.
Blame the campaign manager for that. Or you can try reporting such people in "Meta" as well if you have time to make a list. Such people can the be exterminated in public by the mods

Many posts are very similar and distributed over a variety of threads, mostly in Altcoin Announcement, Altcoin Discussion and Bitcoin Discussion.
Its a sad reality that those sections are the love-making hideouts for the bounty spammers.
Why not allow signatures to be applied at a certain level (for example, from Full Member)? This can prevent many useless posts and improve quality a bit.
I am sure this was suggested before but theymos did not officially do anything as such. But campaign managers are enforcing rules of minimum rank for eligibility.
