We have been told in the past, that if we do a small, free offer, and it doesn't credit, that we are allowed to try it again. Is this considered fraud?

I personally decided to cut out the other rewards programs I was doing, and just stick with one. This though, was partly due to laziness on my part. I don't want to keep track of what offer I do where, and not repeat them. I know if I just do one, then, it will tell me if I've already done it.
