Where he forgot to switch his account before posting "ok Nancy". It's pretty clear.

Back in my day, when someone copied someone's name and pfp, mods would close the account, not tell you to email support.

In fact one time I did it as a joke, not even to impersonate a guy or anything mean... I added a mustache to the pfp and chose a similar name and said hi in one of his topics to be funny... it was closed very quickly.


Block each one. The active posters are really those that "make" your reputation and they've all heard about this, I would assume.
Why's that dude hate you so much to do all that to you? Do you know him in real life? Did you kick his dog? That's alot of effort on his part to harass someone he's never even met. It's weird.....
He could be the Brazilian John wick?
So J, what did you do with his car? Otherwise it's just not worth the hassle man

Like the dude has had dozens of accounts.

Nah, that's not you.
Capital i and lower case L look the same.
