I've tried this a few times...with limited success. I will try this again, hopefully with better results.
What we don't know is how many sites they originally contacted. They could have contacted hundreds or thousands, and even with limited success, they do add up. The only drawback is they eat up lots of man hours.
I've found that in cases where they don't add a link, it at least allows me to "start a relationship" with them to propose other ideas. Fortunately, we sell products where we can have affiliate sites linking to us, pay a commission, and still make a profit. So in some cases cases, I can at least turn nothing into something.
