Mods never got back to me. If you're just trying to offload balance you can always gift hearthstone packs or sell wow gold (purchasing it with your balance first) I was just inquiring about this as it removes a step from the transaction making it safer for both parties.
I don't see why it would be considered illegal as gifting anything on there that someone would purchase with the balance is legal, so it should be, but I cant confirm this. You can try reaching out to njaguar yourself, hell just forward you to someone else who doesn't want to help and ask you to ask again later only to not respond

I just went with pack gifts.
