Comment anonymously with three clues to who you are. Make them hard. Then I’ll try to guess. If I don’t get it right, comment with another anonymous clue and I’ll guess again. If I don’t get it right then, go ahead and reveal yourself. 
Good times.
(Limit 10!)
Limit’s been reached! Thanks everyone. Some of these are very hard!
