WOW, I didn't get the PM luckily but that is so unfortunate that somebody feels the need to act so cowardly with the intention of hurting others.
I really don't understand ... if you hate a website, just don't go on it, simple as that. If you feel so strongly you'd be willing to stand behind your word and show your face (or name or whatever).
Well, to all the admins, thank you for all that you do and all that you put up with for us!
