The problem is that many users accuse different platforms without any proof or when they are blatantly wrong, in that case they are butthurt when you tell them were they are getting it wrong, and they accuse you of supporting the platform.
Regardless of what @OP thinks, I support the suggestion to remove it from that board. Usually, the responses to scam cases are general (it's paid) and don't help much in solving the problem.
It will make scam and scammers hide, because when you disable signature in those boards, people will rarely visit them. So, so many accusations will go unattended to.
So you admit that the primary reason is paid posts?

In my opinion, in cases of scam, getting three helpful replies (advice) is better than 100 generic replies.
