As a campaign manager he reserves the right to kick you out for that if he think that you are one. He does not have to post any kind of *proof*. You might think that he could abuse his position this way, well any manager can. However, their career would be short lived and their rep. probably red.
if he abuses authority as manager, then does he make rules for participants only limited to regulation ?
if that's the case, it's a shame. this is not the right way to make him more famous.
