There is no such thing as Bad Publicity.
Rep's and these forums are some of the BEST FREE advertising for the Manufacturers.
Reps in many cases are like a gateway drug. Many of us own Gen's, or move up and on to Gens. To squash this community would be dumb. Especially in the current economic climate. True, some will never pony up the $$$$ for a gen, but wearing that rep Rolex in public ~might~ cause an average person to buy a Rolex.
It is not until the math works in their favor that anything will or should be done. If reps turn into Napster/torrent equivalent popularity, maybe then we will have a problem. In these economic times it is not even worth it to pay their lawyers.
As for PayPal, the ONLY reason they would be here is if they are "investigating a specific dispute". They are NOT in the enforcement business. They only "React" when needed. They are not paying someone to actively police this stuff. Remember, to THEM, the more transactions that flow through them the more $$$ THEY make as well. Ignorance is bliss in most cases.
