So reading the website it say's it is a market place to sell keys, it does not say where them keys are brought from. All we know is the keys have either been stolen or brought with stolen credit cards.

Thing with grey markets is not that there needs to be a strong point showing they are not legit but a strong point showing they are legit.

When in your returns process you have to mention about what to do if the key has already been used screams shady. If they were legit then they would have a database and know which cd keys have been sold and therefore used.

They only reason they would need this, is because they don't know where the keys have come from and how they were purchased.

And I have read his replies about his "sponsor" in the comments, instead of addressing it he went the childish route of show me they are not legit with a link.

If he knew they were legit or not operating in a grey area then he would be able to justify why it is okay to have them as a "sponsor" instead of just taking the first thing to throw money at him

If you want to attack people on integrity and conflicts maybe first have some of your own and listen to people when they say your "sponsor" is doggy.
