Help me) Someone keeps trying to pick fights with me

It's really annoying every time I play the game, and I want to break away from them. But if I just block them and remove them as a friend, I feel like they'll just create a new account and find me. Is there anyone out there who's a bit bored with Roblox lately and needs a dopamine hit, who might be interested in charming this person and dealing with them on my behalf? They're a bit mentally unstable, so they'll probably fall for it even if you talk to them without thinking. You could even just use them for flame wars. If you're interested, please leave a comment ㅠㅠ I'll give you my Roblox ID, and when that person and I are playing together, you can just join me. Please, someone take this person away from me...
