This, unfortunately, is not an uncommon occurrence. This person has been doing it for years and just comes back with a new account every time they get banned.

Didn’t notice

God damnit not again! Seriously what is wrong with this person he has been doing it for years...

He's just some random alt-right troll. Pay that user no mind. Besides, if there's any consolation, these incidents are becoming gradually less common, so maybe we're past the worst of it
