It seems like at some point I had signed up for Yahoo Publisher Network (YPN) which was a program similar to Google's Adsense. Yahoo terminated the program recently and apparently they sent final checks (or is it cheques? Whatever) to all affiliates, active or not.
I just happened to find my Yahoo check in a pile of mail today and it was for a whopping $0.00. I wonder what my bank's reaction would be if I try to deposit it.
Since it has become customary for site owners to post pictures of their affiliate checks to prove their earnings, here's a picture of my Yahoo check. See, now you believe me? 🙂
