Some people in chat were wondering, so here a list:
newpuritan had 2 multi accounts: gardenvariety and dude0001
Both new accounts were banned and newpuritan confessed afterwards.
Dantes Fate also had 2 multi accounts: lolpwntlol and Powntup
Both new accounts also banned.
The Dont also had 2 multi accounts: Doomed Soul and DeathStarss
Just like above, 2 newest accounts banned.
I'm investigating 5 more multis. Will post here after taking more actions.
