Some people might not know these sites but I think you don't need to post this since a lot of gamblers here already know where to go. Another thing is that there are a lot of signature campaigns here on gambling sites, people could just click on it.
I don't think so. Maybe those ordinary people or person that are not playing or gambling, maybe they don't know that but for those who are betting and gambling daily or those gamblers they probably known that for sure because if you are a gambler you must know every gambling or any gambling that may helps you to earn profit or money.
How would someone know a lot of gambling sites would earn profit or money? If that is the case there are a lot of people here that already earned a fortune with that, to be honest. It is not that I don't like knowing new gambling sites but I don't really like playing to other gambling sites that I am used to unless it is trustworthy and already built its reputation in the long run.
