Have you ever wondered what the bitcointalk forum would be like without signature campaigns? I have thought long and hard about this question. There have been numerous controversies regarding post bursting and spamming just to meet the weekly post count and other vices on the forum, all in the name of joining signature campaigns. As a result, many users have faced punitive measures such as temporary or permanent bans, registration tags, and more. The reputation board, which is the court house of the forum, is brimming with disciplinary cases, most of which are related to users in signature campaigns.
Therefore, I ask, what would the forum be like without signature campaigns?
Would it be more sanitized?
Would it be less filled with spams?
Would there be fewer alternate accounts?
There are other platforms that doesn't have any signature on them and guess what? They still has some problem and I don't think it's the signature is the problem here it's in the users and since there's an incentives when wearing signature and/or avatar of course, you'll see a bunch of them wanted to take part if there's a reward. That's why there are certain rules that are unofficially implemented for such thing thus, having rules broken will result in a different types of consequences.
I think you have to experience it for yourself to know exactly what would it be like by trying different forums.
