Really, if anywhere it mentions Purebullshit why does anyone respond? I wouldn't if it weren't for the fact that people who I know aren't promoting them responded.
Just don't respond! Let the phony promoters post and let the thread die. I'm guessing they are hurting for subscribers and now they are getting free promotion.
I've been looking into some interesting ideas for this ilk of scammer, or the like in the back of Futures magazine, and have been handed some good ideas by lawyer friends. A couple of buddies from the good old days suggested some other options, but probably not approriate, lol.
