Is there any system in place to prevent a user from clicking on his/her own referral link multiple times and getting multiple rewards?

Yes, we have an Anti-Cheating system to prevent users from clicking their own links and being counted as a referral. However, this protection is not foolproof for the truly dedicated cheater.  If someone is trying to outsmart our Anti-Cheating System you will be alerted by a red triangle next to the persons name.
