Who was the troll?
Don't know him. Somebody with a grudge on me, no doubt.
He's been around on YT for ages just doing that sort of stuff to random people under various 'invincible' names. It was fun to watch you get to him
However I do think it's a bit strange that this is his hobby, and that he actually seems to take it seriously and go full out.
Also the projection thing is eerily blatant. He really doesn't know what the rest of us do
I wouldn't rule out a possible stalking seeing as you got the better of him.
(lol, reading this back it sounds like he's me/ I'm him. Dunno why)
