Parasocial relationships are incredibly unhealthy.

TotalBiscuit even tried many times to dissuade them when people he did not know got too interpersonal in the chat. After awhile hearing how chummy people were getting now and then, he'd just get a serious tone and say "You mean nothing to me. You're a name on my screen. I don't know you."

And of course people started hating him for it. But if they had thought about it, what was really going on was him trying to point out that they only know a fraction about him, what he puts online, and he bluntly doesn't even know who they are.
