Joshua Connor Moon 

a.k.a Null. This person runs a website called Kiwi Farms that is dedicated to doxxing, harassing, and gossiping about mentally ill and eccentric individuals deemed "lolcows". But ironically or perhaps not so ironically, he fits the definition of an lolcow himself due to his rather sordid online (and real life) history.

The idiom "pot calling the kettle black" fits Joshua Connor Moon perfectly.
