I'll have to agree with Chris here that that's probably one of the biggest no-no's when it comes to operating a forum.

Extremely unethical to sign me up for a forum that I had not registered for. Not to mention the legality of it isn't straight forward considering to register on the forum itself we had to agree to a terms of service and privacy policy - to which each site has their own iteration of this thus requiring us to agree separately.

I'll make this my formal request to be deleted from the "SSS" forum.

Good luck with the sale, but you've just cause your sale price to drop considerably.
