1. Using pictures, graphics, text that don't belong to you unless you've been given permission by the owner.

2. Cloaking to scam search engine traffic.

3. I do think that when I click on a thumbnail in a TGP that I should get a gallery, not another TGP. Just because everyone does it doesn't mean it's not cheating.

4. Selling anything that you claim increases the size of a penis is cheating.

5. Submitting a page to an AVS and then changing everything two weeks later to funnel traffic to your paysite is cheating.

6. Hotlinking anything without permission is cheating.

7. I think killing the surfer with more than one pop-up is cheating. The surfer has, after all, indicated by closing their browser that they want to leave.
I have to agree with that..

As to the skimming, sad to think that simply because it's done so often its considered okay, sort of like saying well he's a little bit pregnant.. either you are or you ain't as far as I see it.

I do think that if in the submission guidelines it clearly states that 1 out of 10 or whatever clicks will be redirected and I submit, then fine.. i have agreed but to do it without telling.. well to me that is cheating.

just an opinion
