I think it is time to test affiliate programs on how they dealing with the database of the players we are sending to them. I have registered a few casino accounts as a player and later on got lots of spam on my player e-mail address. It means that some casinos using our players e-mails to avoid payments us as affiliates. Gradually in terms of rev. we are loosing the players and the revenue.
The idea is to reg. separate emails for each casino to sign up an account, as soon as the casino would send spamming e-mail, post them on the forum to let everyone know if it is worth to promote such casino.
