Did you just incriminate yourself in using a alt account so your main account can plunder it? If Oasis wants to, they can ban you since that's one of their rules.

Of course its a common thing. I'm just saying you pretty much told that you plunder your other accounts with proof. It's like how weed use is common but if you do it in front of the police and if the area you live in have drug laws on weed, then you'll be punished, so I'm not being "naive". Whether or not Oasis actually does something is the issue since sometimes it seems they don't try hard enough on following their own rules.
