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.
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.
I do gamble even if i am in a gambling campaign or not. There are many people who are in the gambling campaigns but they never gamble. You need to have some knowledge of gambling to be able to discuss about the gambling but even if you do not play in real, no one will ask for it. Its your personal matter whether you want to gamble or not.
Because they understand the requirement, but unfortunately some of them don't understand how to gamble.
Maybe they will learn along the way, and that would be a good news so we will only read here real and valuable information of the posters.
Being a gambling board poster, I can only see few people who shared the same interest of mine, majority of the people are just discussing a general topic but not on a specific games or events since they don't really gamble.
