I read comment by the admin that if the merit system fails to reduce spam from the website, he might take decisions like removing the signature campaigns. This is scary for me. I am not eligible for any campaign yet but I was hopeful to get enrolled in one. If this is going to be implemented for sure, I might not be comfortable participating in discussions. I will though read posts by other members for information needed.
In my opinion, without signature campaigns, the rank of this forum would decrease so it's unlikely signature campaigns will be banned on this forum.
What do you mean by rank? Like Alexa rank? Who even cares about that, yeah the traffic will surely decrease that's the main reason I believe why theymos hasn't removed signatures yet. More traffic = more ad revenue, but obviously he can't just sit and see the forum filled with meaningless garbage so I think this time he is seriously considering about this.
