As a fellow Kirby I would advise you not to give him any more attention (It's what he wants) Block and ignore him no matter how far he takes it because it's the only way he will stop
I have been not to give attention by blocking him, but because he's being mean to my friends, that's where I have to pitch in to save them... But still, thank you for the advice!
The thing is if we stop it could also make him think what he is doing is okay... so it's hard to find a right way to fix this situation or he could keep going u till we stop ignoring him
