Daji dared me to post this in the public forum, so here goes. Think well of me when I am gone.
So far, the only person who has evidence pointing towards them is EndMaster.
Evidence for:
1) "lol fag" is kind of his signature line.
2) The first thing you did is rate all his games.
3) Malk didn't immediately ban you, despite knowing you were an alt.
4) You got 1000 points out of nowhere. I'm pretty sure lesser admins can only transfer points, not pull them out of thin air, and when I checked all the admin's XP pages, nobody had recently been docked 1000. That suggests a higher level admin.
5) After reading her wikipedia page, Daji seems like the kind of alias EndMaster would pick.
6) You knew the name of Avery Moore's second account, confirming the "longtime CYS member" thing.
7) You made an implication about my mother, which is also EndMaster's signature line.
8) In the history thread, EndMaster said it was someone in this room--I took that to mean the thread. The only three admins there are EndMaster, mizal, and hetero_malk. I doubt it was hetero_malk because he wouldn't yoink his own points, and though it could technically be mizal, there's no other evidence suggesting it was her. Also, if it's not EndMaster, he doesn't have any motivation to provide clues to their identity.
Evidence against:
1) EndMaster has an absolute power admin account. Why would he need an alt?
2) If EndMaster wanted to say "lol fag" to a couple noobs, wouldn't he just use his main account?
3) Other than shits and giggles (which would be valid) I can't think of a motivation.
