Pwned vs. Pwnd

I see most people using pwned instead of pwnd. I personally use pwnd, as it has the second largest amount of hacker-talk confusion of the "word" pwn in past tense, only second to that of "pwnt"...it has just the right amount of it.

I quick use of the forum's Search function reveals that 80% of the time that someone has ever used pwnd, it has been me.

So which do you prefer, and why?
