guys you should stop panicking. Keep in mind, that of course he cheated many of us by not paying what he promised but remember:
No matter if you have signed from referral link or not you are paying the same taxes (to admin if not referral). Thus you are losing nothing by playing as his referral. But since he not behaved nicely i suggest to just create new game and start again with more knowledge than before.
In this situation i prefer pay taxes to admin. At least he isn't the one who cheated me. If OP won't answer till midnight i will contact admin of GT and ask him to remove all refferals from his account. This way should be fair.
