only few hours left still not minimum of 30 participants apply for this contest. 
We are 1 short
I see all the newbies applying and I think we shouldve added a rule for btctalk acct must be a certain rank to join. The problem with that is some of our players were brought to us via twitter and other advertising methods. So theyre legit new accounts. thenitro and CHelat are 2 of the bigger players on our site. Id have to look into the others, but i guess my point is we wanted the contest open to anyone. Didnt expect the contest to be taken advantage of. We will try to consider this on future promotions.
I think it is only fair to exclude newbies you are not able to verify. You can accept entries via other media, or use them to confirm newbie entries here.
If newbs win all the prizes, it will not appear fair to honest participants. A little more so if the drawings aren't provably fair.
1. People Trying to cheating of the contest.
2. They're Real.
As spelled out ndnh when the winner is newbie it's like to unfair (1players). We also must not prejudice, Contest's running only on forums bitcointalk then allowing for new players who sign up here to join contest. I really have not more idea, I'm just trust contest running as fair.
Goodluck everybody
How would you suggest we combat this?
Regularly perform IP checks on all of the accounts that enter a promotion. If you find a multi-accounter, freeze their accounts, confiscate their winnings from promos and ban them forever.
Newbies can be both legit or cheating as Zoel said. I am not against clean newbies entering a competition, but the thing is that newbie accounts are so easily made by anyone. That is why you should keep an extra eye on newbies if you decide to let them participate.
It is better just to exclude newbies. TBH, I (or anyone) can create some newbie accounts, I don't think you will be able to find or flag them.
The competition is decided by our own roulette wheel. Its totally random. Going by your logic its impossible for a newbie to be a legit account?
How are you conducing the draws?
I assume you decide which roll decides the result. In any case, won't you know the rolls for the day by the first block of the day?
It is possible.
Your promo. You decide the rules.
