If you haven’t already you should probably add this to the ‘Bug Reports’ Forum, I have witness some streamers (specifically on Twitch) who’ve been getting harassed and trolled by people doing that exact problem and it really sucks to be honest. I mean, trolling for some harmless fun is OK (obviously) if it doesn’t affect their streaming career like spamming a quote a streamer made or a funny moment that happened on stream that becomes the “meme” of the stream, just for some smiles and giggles, is totally OK, as long as it doesn’t hurt them but, to the point where it could get them suspended or banned from streaming? That’s just so dumb and pointless to just go around, wasting your time making an account doing that. 
(They can also turn off Friend Requests if that’s an option, also sorry for the rant
