Hi rupe,
That's bizarre. Like Auctiva, Sellathon is an eBay Certified Solutions Provider and the link metioned in this message is certainly in accordance with eBay rules and regulations.
My guess is that this listing picked up by some automated listing scan and got grouped in with other listings that were to be pulled from eBay for some reason. I definitely suggest you contact eBay support with regard to this issue. They should be able to shed some light on the situation.
