I pointed this out before, I got a massive rush on one of my aff links and had no idea where it came from. 
It was only the aff links I had on a PR3 site, none that I could find on the lower PR sites, and only if you searched for the EXACT anchor text, since there seems to be a little confusion over anchor text (least in my recent exp), I mean the text link, like the anchor link to me the text in the link. Sorry if my clarification is unneeded but best to be clear 
So if my anchor link was "Cheap Drop Catching", the bing aff link only came up when searching for EXACTLY that, not "Cheap Drop Catcher", or "Drop Catching Cheap". It seems Bing is truely going for the most relevant link to a site, i like this as the results are ALOT more relevant
