Recently, he tried to come back again, this time with about 18 more alts, all quickly banned by Egglord1. Also, was doxxed by @13232ljkop , that was banned soon after.
Additional Details in progress, will be written below.
From my personal experience with him, I had contact with him some weeks ago, but I didn't know that it was him at first. He went by the name of I'm ze partygoer on Discord.
He wanted me to promote his Discord server, that had him, an unknown user and a user that was banned for 1 day here. At first, I was really suspecting to be him, as he mysteriously was IP banned for no reason from the Fandom site.
I ended up not promoting it here, as I didn't know him. Later, he revealed to be Coolcolapple, as always.
Yesterday, I recommended him to forget the wiki for now, and to come back when he was older. He said that he would be a "wiki representive" (?). Guy also said that he made a new sneaky account, and that I probably need to secure every wiki.
He also said after that (with his own words):
His emotion has been controled;
He has improve his grammar real well;
He won't impersonate users anyomore;
That I said that some users can get in to the wiki.
To explain the last part, I was talking about enforcing the age rules.
