I guess anyone can say anything on this site. Apparently, you can even accuse people by name of illegal activity without providing any details whatsoever. Personally, I'd be surprised if that's not illegal.
And, of course, it's all done anonymously.
It will be very interesting to see if pissedconsumer.com publishes this "complaint." My guess is that they will not.
My guess is that they will also not bother to take down the comment just prior that accuses the CEO of being a "white collar criminal."
For a company trying to pass itself off as a watchdog for unethical practices, I'd say pissedconsumer has a lot of work to do to on itself. I wouldn't be surprised if this entire site is not simply an extortion racket, not that I'm accusing anyone of that.
