I'm not sure why your having this trouble with all this spam but it's cropping up on a regular basis. Perhaps it may be an option to ask some of the trusted members on here to do some moderating for you. I'm thinking about guys that visit that often, dont have any commercial interest (no pay site or clip store owners) but would be happy to delete spam posts or approve members and so on.
A useful site I found that helps control span is this
http://www.stopforumspam.com/Now at our forum, allfetishforums.com, we approve members daily but use the site above to vet them
cheers
