I'd have liked to check it out, but it's another one of those Facebook sites. I don't do Facebook.
A stalker from my past managed to upset me just by asking for friendship through Facebook after I deleted his email as Spam. He even joined again in order to do it again after I deleted as Spam the request. Each time leaves me upset for at least a week.
I finally managed to cancel my account with them, but have still received requests for friendship, once by a direct email from a stranger. I delete these as Spam, but apparently they use different addresses.
It also bothers me they are everywhere. I feel like Big Brother is watching.
