As we said before, please try to be patient... Never Ever open the smut mails.
Three other forums I belong to are being bombarded as well. I did a Google search for one of the unique, cleaner title words in one of our messages & got thousands of hits primarily from all sorts of forums. It is not just us, by any means.
I located 1 or 2 apparent owners of sites our smut mail is pointing us to. I gave them enough info that they could identify their "client", if they were so inclined. Enough complaints (or claims that children are being subjected to pornographic images & messages) sometimes get some results. ie: the "boss" tells his little fishermen to go spread their message elsewhere. Obviously, I haven't had any success yet.
Just keep your good humor, & patience. & ignore ignore ignore the junk.
