EDIT: Nevermind. The prize is given out to accounts that barely have any posts, and only post in giveaways and such, instead of actually rewarding people who do post often and do actually provide useful advertising.

10 for signature, 30 for links, I believe.

Very good question. I'm working on this right now this is my first draft:

- All participants will get a number from 1 to n in relation to their nicknames in alphabetical order (participant list here)
- Random number RND will be the decimal value of the last 8 characters of the first bitcoin block hash on the drawing day
- Winner is the participant with the number (RND modulo n) + 1

is it ok?

No, bad. Using modulus will skew the results, allowing some people an unfair advantage. Unless 'n' is a divisor of the maximum possible value for RND, skew is inevitable.

oh right. the advantage would be negligible low but nevertheless making it divisible will do it:

Code:

$winner = floor( hexdec(substr($hash, strlen($hash)-8, 8)) / $n) % $n + 1;
