It would be nice if PD make deposit no need confirmation but withdraw are needed 1 confirmation like the old time 
What's the problem in allowing instant deposits if you need many confirmations to withdraw? Is there any possible negative consequences? Still I suppose wiaitng for 1 confirmation isnt too bad but being allowed to play straight away was great.
Yes there are. Coz then some bots deposit, and bet all in if they win they wait for 1 confirm to cashout , if they lose they double spend that deposit , and it never gets confrirmed. So pd loses that deposit.
This is what happened in early June to make Stunna changed his mind to only credit the deposits after 1 confirmation.

Was this coming from those accounts with random character names making a single bet of .1 (or however much it was if there were more that weren't on the high rollers list)?
Not too sure. Quite possibly.
If I'm thinking along the right lines I think the attack have gone like this:
1. User 'deposits' by sending a payment to an address
2. User bets with that deposits
3. a) If it wins, let the deposit confirm
b) If it loses, attempt a double spend to an alternate address that's owned by the user
4. Rinse and repeat, to win.
Would this be the right idea Stunna?
Pretty much the idea behind it
