I try not to respond to trolls. I've learned blocking. If anybody is truly mean to me, or says something arrogant - don't respond, you'll only empower them. If you give them anything! So I'll block 'em. Or, if someone's annoying, but yet I still kind of like them, I mute them. Because they don't know! So then, it still looks like we're connected, but I don't have to listen.
