I tried to set up a new account using my other main email account, but it seems they know that one too, so I'd need to make a new email up.
I'm torn. I don't post much, but I do like to keep an eye on what family and friends are up to, otherwise I would just delete my main account (if I knew how to!)
But it seems that this type of social networking is the future of the internet, so like it or lump it, it's here to stay.
