What re you trading for, then?
Nothing, it's more of a gift of service.
In the past, similiar to this has been posted in Trading threads, so unless some policy changes have occured, this is nothing new.

This is explicitly against the rules, and continuing to push the point is going to get you some real bad juju. If I were you, I would edit out those posts.
