today I also found some cheater who has applied for twitter campaign using my btc profile.

Maybe the best thing to solve this kind of problem is to report it into the bounty manager because they are the one who facilitate the number of participant and the type of participant that are intended to join. If you show a good proof that they did some violations in rules of the given campaign then maybe it will be remove those kind of not legit participants.
