I was previously under the impression that selling these keys is against federal anti-piracy laws, however I have not been able to find anything to back this up to date. I have also been told that it is not against anti-piracy laws (also without reference).
Tell me how to reference the nonexistence of a law and I will do so.
I think it is somewhat of a moot point now as shorena has pretty much taken care of it, at least from a EU prospective, which has resulted in me firmly believing that the negative ratings are not appropriate and should not be seen by default. However if you wanted to strengthen your argument, then you could cite US anti-piracy law, and what
exactly it prohibits and then analyze what the law prohibits verses what these sellers are doing. If you really wanted to put the nail in the coffin then you could do the same with Canadian law (Vod lives in Canada).
I think what Vod is doing with these sellers is very similar to me giving a negative trust to a competing account seller solely because they are a competitor of mine, or you giving a negative to someone who sells silver only because they sell at lower prices, or Smoothie giving a negative only because they are a competing coin dealer. In any of the above cases, it would be fine if any of the above gave a negative to someone that is actually scamming or attempting to scam (stunna does this all the time with his competition when he finds shady gambling operations - which is appropriate).
While I do agree that Vod has provided a service to the community for spending a lot of time tagging a number of scammers and potential scammers, I do not think this means that he should be held to any less of a high standard to be fair with his ratings.
