I was continually bombarded with sites that totally ignored my link criteria.... and this was one of the so called more professional outfits. It turned out the focus was totally on link volume, not quality. A total waste of time and effort.
Expect to be flooded with link requests from MFA and pure affiliate sites.

I joined one about a year ago, and at first WAS bombarded with junk requests, but after a while that stopped. If you decide to try it, the key I think is to be sure to do 2 things:
 If they have filters, only pick the exact categories that complement your site; and  Do not be tempted -- reject everything that does not meet your own stringent criteria. Pretty soon your ratio of rejections to acceptances will make it obvious that you are not interested in anything even remotely irrelevant.
BTW, with me the jury is still out as to whether it did any good -- I'll give it a little more time, but not much.
