Uhm..... you mean like... putting an item in for 100YC and having someone buy it from you? because... that's why there is a YC button! But beware they deduct 20%

It's fine to put an item in for yocash and have someone buy it and give them coins for the process. I think some people got banned for this a while back when BVG was looking for people with hacked yocash (no transactions of yocash purchases), but as far as I know they got unbanned after explaining their situation. I never done this just because I was nervous about it but it should be fine.

You can't buy yocash in the auction house. You can sell items for yocash though.
