z, you apparently don't understand.
When they do it, it's cool/funny, etc. When you do it, it's proof that you are a fool.
If they spend years making 10,000 posts about you, they are doing a public service by pointing out your foibles. If you make one post saying, "Gee, it sure is odd that a bunch of people I don't know have made 10,000 posts about me," then you are a stalker who is obsessed with them.
If they contradict themselves hundreds of times in the course of ridiculing you, well, that is irrelevant. If you point out the contradictions, even once, you are a loser with no life and no sense of humor.
Hope that clears a few things up.
