I understand your frustration about how some threads go "bad". Still, have you considered the unintended consequences of forbidding any discussion of / comment about other member's posts in Consumer Reports?

Given that rebuttal / comment / discussion is now forbidden, I predict that your policy will enable some amazing slander, smears and outright lies about targeted vendors. I hope I am wrong, yet....... You might have effectively hack-sawed the brakes off of that train.

Well, it was your decision to make. The consequences will be yours. (thankfully)

Good Luck,
