To help you out, here’s a little cheat sheet of what NOT to do:

1. Don’t sell beta keys in an online auction, message board or anywhere else (the opposite applies as well: don’t buy beta keys, they won’t work). We gave you that key and for you to go re-gifting it. No re-gifting!
2. Don’t put our ad code on sexually explicit sites. It’s very naughty.
3. Don’t duplicate (*cough* STEAL *cough*) content from other sites. We want to be with someone original.
4. Don’t place images next to ads. It’s dishonest and we want to be in a long term relationship with publishers everyone can trust. People will think those images have to do with the ads, and when they find that the site they’ve been directed to has nothing to do with them, they’ll be pretty miffed.
5. Don’t block the crawler. It keeps us from getting to know one another and is bad for both of us. Honestly, your blocking is not helping.
6. Don’t go nuts with the ads and place them all over every page like they’re your content or something. It looks like you are trying too hard.
7. Don’t manipulate our ad code. We’re flexible and already offer plenty of choices.
8. Don’t send us traffic from Zimbabwe or Ireland. Not that there’s anything wrong with Zimbawe or Ireland, but right now we’re just not ready to make that big, international commitment. We’re working on it, though, so be patient, and good things will come.
9. Don’t use inappropriate ad targeting. If your site is about flowers, it’s not cool to be targeting finance.

That's all I can say.
