Isn't attraction about feelings?
From what I know, Marty is Marty, hasn't sold out. Still the weird guy spouting random stuff from the back of the class.
Most of the current posts from the Marty-account is not him at all.
It may be that Marty uses the account some time every now and then but 99 % it's Joon on the account.
Different wordings, grammar-use, vocabulary etc
Joon have of course read Marty's old posts and tried to emulate but there are things said/written by the Marty-account that isn't him at all.
Things that real Falcone definitely should have known and remembered.
