Anyone have any suggestions on this?

I'm using the Buy.com datafeeds directly from Buy.com. I'm getting extremely high click through numbers, say 13k last month, where I only had say 300 visitors. Because of this my Buy.com access is getting terminated. I've responded letting them know that I don't have a good explanation and provided impression/click/order counts for a similar LinkShare based datafeed.

I'm using Wordpress MU as a content management system, I'm not pinging the Buy.com purchase link as I post. Does anyone have any suggestions as why/how I could get such a high click rate with low visit counts? On LinkShare datafeed based posts I'm not having this problem. An example of where I'm posting to is sports.wslrss.com (please feel free to remove this link if it is not allowed, I believe it is directly related to my question).

Thank you, iolaire
