Hello yes this is illegal how dare you make me think your avatar character looks so handsome. I literally just discovered your content today. How do we proceed.

Gave my answer on Twitter about this. Not sure if it's the right one.
Compliment sandwich but without acknowledging them. If they won't listen to reason and or they are there just to mess with people then say the simple word "Bro, that is sad" Talk to the kid and introduce him to a better environment.
Hope I can do all this though. Pretty much work too much.
