We have begun to receive weird messages from a site called "tagged"

It has our paid email addy, our true name, area we live in , & even a pic of us that must have been stolen from one of our photobuckets, because we have never sent it to anyone

As we never joined this site we have no idea what the passy would be supposed to be & it won't let us delete the account coz we don't know the passy

We are terrified, some of these ppl live quite close to us, & they are men

Can anyone help us with this ?
