I would like to say in conclusion that there is no reason to do anything against the UMG oorply. As long as the UMG stays within the limitations of the IMG ID, everything is okay. And I have not seen anything that would go against the ID. Not even the "cooperation" with the Liberty Rogues because it is no alliance but a "we pay you, don't hurt us" relationship that is rather normal when we think about criminals.
I would like to handle everything else in roleplay.
Irply, the IMG| hasn't even heard anything of the UMG yet. That's no surprise, as we do not operate in Liberty and will not start operating in Liberty. Once the IMG| comes to know about the UMG, we can rp and see where this leads.
Oorp critizism before anything happened is perhaps not the best way to deal with a new concept. Of course I can see potential consequences of unlawful actions, but being afraid of potential problems before the rp even started is not really conducive to a creative roleplay environment.
Consequently, I wish you good luck. Feel free to initiate rp with the IMG| via forums, or contact us ingame if you want to rp. If you do not want that, but stay under the radar, that's also perfectly irp.
