In order to be successful in a gambling signature campaign you have to know gambling as many of them need as a requirement that many of the posts to be made in the gambling section.
Exactly, how can someone participate in a gambling discussion and promote a gambling related signature if you are not familiar with it? Personally, I have been into gambling way before I found crypto and this forum.
Therefore you have high chances to be accepted in a gambling signature campaign if you are a gambler with experience.However I dont think applicants who start gambling only to be accepted in a signature are not the best ones and this is not a proven record.
Still up to the campaign managers though. Anyhow, we are at an advantage if we frequented gambling related thread and have discussions with gamblers around. And we can truly see those posters who have gambling related signature posting in this board that have the experience. The post has substance or at least as fellow gamblers you grasp their knowledge.
