Don't feel bad. A LOT of people have been blocked for not using her links. I was just blocked a couple of weeks ago for not using the link. You would think Sheryl would be happy just to receive winning bid posts.
It is unfortunate that BFT was a good resource to use for priceline, however the site will suffer for lack of posts by all the people she has blocked. The other site betterbidding.com is good, so hopefully more people will post there.
