I mean it's no secret that people shitpost for sig campaigns. I think if we put a cap on their earnings, for example, once you've earned $5, you need to stop posting.
This isn't a freelancing place where people will stop doing what they do once they get paid. Limiting someone to post eliminates the whole purpose of a forum intended for discussion, regardless of how gruesome and clusterfuck of a spamhole the forum is. If there were an actual way of stopping spam, there'd be also no trolls, no memes, no nothing.
Also, impose bans on account sales on Bitcointalk, so people don't buy accounts to bypass restrictions on Newbie users that are there for a freaking reason
I mean, if you can buy higher ranked accounts, well that kinda defeats the point of having ranking systems now doesn't it?
Sorry, I'm gonna keep this brief. I know there's been plenty of talking on this issue already.
How can anyone impose bans on account sales? Admins definitely don't have the time to investigate all of the 2 Million+ accounts here, and people sell these accounts all across the internet.
Sorry to break this down to you, none of this would actually work or help reduce spam. Its good that you're trying to find out possibilities to stop or reduce spam, but just know that if it were possible it wold have been in action by now.
