..and..they all have the "Satoshi Karoshi" signature.
Is this strange only for me?

I ask that users to explain their position in this situation Smiley

This is foul play - disqualify them.

They've done 10 posts for link signatures, 1 post in this thread, then 1 post in the CoinVictory thread...and they all have spam posts.

Was about to post this, can confirm that they are most likely alt accounts, and using duplicates for a higher chance.

Thank you for this information! We will check this! If they are scammers, we disqualify them!

@nicolazza: Do you get answer from this users!? (I ask that users to explain their position in this situation Smiley)

I am very disappointed that some user play a false game to get more chance to win ... 0 tolerance for this...

Wait, you're not vit1988, are you from Satoshi Karoshi too?

Again, another spammer.

Could the OP please manually disqualify these alts/spammers?

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;

I'm pretty sure that still introduces skew, because it doesn't look like that makes the maximum random value divisible by n.

The correct way to do it is to discard "bad" random values. Something like this:

Code:
do
{
    retval = GetRandomNumber() / ( RAND_MAX / ( n + 1 ));
} while( retval > n);

Very good question. I'm working on this right now Grin 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
