I'm starting to sell some of my CD's on eBay and was wondering if there would be an issue with me posting links to my auctions in artists shoutboxes on Last.fm?

Would this be breaching anything? Just wondered as I've never seen anyone do this before and I thought it seemed like a good idea in trying to shift some stuff, aiming directly at people who may be interested.

I don't really want to do anything to risk getting my Last.fm profile deleted though. Advise me, people!
