You can privately freepmail the "Admin Moderator" and ask for advice..I doubt there would be any control..but it never hurts to ask. They normally will reply..just make the subject line ''stand out''. :)
I have gotten all kinds of UNWANTED freep mail (and sent some too:>)...sooooooooo what? I also get junk mail in my snail mail.So what?.I simply FR the person and tell them I do not want any more and that I will not read it..and I do not read it I delete it without reading it
Unless they threatened you or your family physically I say give it up and do not be a cry baby!
