I strongly believe that as long as NOTHING was withdrawn from the website, the cool down policy should not apply.
Otherwise, this would imply that if you make a withdraw from a deposit, you should also get a cool down period
(which doesn't make sense) .
If main balance wager is positive, why would it differ when it's transferred from faucets?? What you are actually fighting are abusive withdrawals and not people who didn't withdraw a thing from the website , so you should be applying your policy when a user ACTUALLY withdraws money from the website.
This is also interfering with the user's free will and coercing them to adopt a specific strategy (Which should never happen in a dice game, a casino maybe, a tv show maybe, a dice game? hell no)
