I Hate Fake People

Recently I've had to deal with a lot of them. I honestly thought that fake accounts would calm down on a site like this, but it seems not. You block them and they come back with another account.
I didn't mind this, as I just learnt to scroll past most of it and ignore messages, but one found me on my other accounts on other sites. Actually said they were a fan of me on SW when I hadn't given out any of that information and they were different usernames. Found it a little creepy.
