Blah blah blah.

Reporting accounts that violate the TOS is within the rules of the game. If that's become an effective strategy in defeating your rivals, so be it. The ones doing the buying and selling of accounts have only themselves to blame for that. What you're saying is both syndicates knowingly violate(d) the TOS, but only because that is being used against you as an effective strategy do you have an issue with it.

Fight fire with fire, in this case. Forum tears certainly won't do much, if anything.
