We are talking about the effects of the mixer ban on the forum, they mainly look at signatures, paid posts and whether someone has written more or less before.

But what about the actual effect of the mixer ban and reduced discussions about mixers?

Here is an example https://bitcointalk.org/index.php?topic=5491818.0 One guy registered to report a potential scam from a well-known mixer here.
A few days ago, information appeared about a problem with this service, so the question arose as to why this user did not do research first. But where should he do research? on a forum where the presence of mixers is prohibited?
Just a couple of months earlier, there would have been much clearer warnings.

Of course, Bitcointalk cannot cover all cases, but it has certainly lost part of its importance as a relevant source of information, due to the exclusion of the mixer.
