I have witnessed something like this. Twice, actually. Both on Myspace. When I first came on the blogging scene there, there was this “top blogger” who caught someone in a big, big lie-the person that made their main account had made around 50 sock accounts so that they could rank in the blogs. Another time there was this woman who claimed to have some sort of brain cancer I think it was. She wrote a blog about how she was in a hospital and had masturbated in her bed after having had brain surgery. Turns out it was a what is now known as a catfish. There was another catfish profile I think. Some woman who allegedly died but people said evidence proved that it was a fake profile the whole time.
It’s amazing the lies people will weave on the internet because they can’t stand their own lives.
