most of them are already covered, only left in my knowledge is : admin and some of it's derivations such as admin123...
1234567890 is also another one I've seen people use. I use that for some of my accounts. PS. No I didn't use it for DP, so don't even try... XD
I think that password123 is the best, and I think if we put a couple of the worst passwords, I get a powerful password, which will not let anyone in. Example: cobrabeach, snaketiger, footballpussy ;D
