You have mentioned in the rules that edited posts will be disqualified, but you never mentioned if users can have more than 1 guess. Lots of users have 3+ guesses. None are correct, but 1 thing you gotta remember to do on this forum is explain everything otherwise people will try anything 
This is what was said,
Sorry, but are we allowed to make just one guess ? Considering the range (10,000) I don't think that even someone will find it!
What if each user get the right to make one guess per day or per week.. set the calendar at UTC time to keep the thing simple, for example each user allowed to place one guess per 24h.. between [00:00 and 23:59] !
We’ll allow one guess every 48 hours!
But I do agree that it should be added to the original posts so that everyone will see it.
