Anyway, even if users become part of those signature campaigns (don't take it personally, I simply try to describe how it works) they influence the others. Moreover, if a beginner comes to this forum and see a Legend member or something like this, the chances that this newcomer create an account via the link from the signature are higher.
Why we wear signature on the bitcointalk forum, do you know? We wear signature campaign as a promoter of the project/site on this forum. The people might be interested for that signature but referral link not allowed so there is no chance to that newcomer will create an account
Signature is a promotional event for them, and of course with their honest attitude, all of us here will definitely continue to support them to develop in the industry, but if they commit fraud against their users, of course these users will easily destroy the reputation of the gambling site mentioned in this forum, I think that's why many crypto gambling sites might think again if they intend to deceive the members here, and one bad example is the 1Xbit site which is now starting to be abandoned by their users after their thread contains a lot of negative tags from forum members.
