I own a link list and that shit happens all the time with sites. Webmasters submit their AVS sites doorway and then switch up the link after about a month. I don't see the point in removing the recip. Fools can just make a bunch of diffrent doorways and move on.
BTW Chirs you should switch up your recip button. It looks funny having a cat at the top of the page. I guess people will click on it to find out what it is!
