Well recently someone made a scam accusation that he couldn't withdraw his coins from the site and they did send him half of his balance (40 btc) but after investigating the users actions on the site they found out he had a way to cheat the system (this happened after the launch of PD4).

I'm not saying you did something like that, but once an account gets a red flag there must be some reason why they are being cautious.

I hope it will be fixed soon. I play on PD for 1,5 years now and never had a problem like this. So I'm curious now as well what is going on.
