A handful of heated comments hardly make a person rude, especially without context of what the other person said. I know it's just a theory, but that's as poor of a defense as it's just a prank bro.
Well, i don't have the exact links, but i remember a comment or two...
1) "Why would I put cringe on my memes you f**king 8-year old"
2) "Nah, i just have a problem with you"
3) "Bro SHUT THE F**K UP you stupid underaged user"
