On a sidenote, is a deal like this allowed?

Server A: I play with my main here and you with an alt.
Server B: I play with my alt and you with your main.

I send you 10k gold on server A and in return you send me 10k gold on server B. No real life cash involved whatsoever.

With a friend/someone you know it's doable, but it's an incentive for scammers of course. Just want to know if something like this violates the tos.

Reason I post this here is that it might save him 1 toon transfer
