And to go through support undetected you should use 2 tools;
1. Mac changer (https://goo.gl/ixFGQD) this is the one i use
2. Vpn ( Open vpn ) or there are tons out there with cracks
The way gm interface in support works is based on your mac address and ip. And it's literally fairly easy to change those by using the above 2 tools. However some good games also check for device id but rom is fairly poor for that tech stuff
If you manage to spoof mac and ip you can do anything you want and should not harm you main chars ingame.
And yes head gms do like to negotiate on stuffs which they don't know. One of my friend got his 15 accounts back which were banned due to involved in duping and he traded the dupe for accounts. I know it was sad :/Wow. So you mentioned you had some dirt on the GMs, and he then offers to lift your ban in exchange for the info, then cancels out on the deal and says "too bad, I'm not following through"? What a slimeball. Liars deserved to be dragged through the mud.
