Hi,
Owner of Double.tf here. We've taken into consideration feedback by the community about vulgar actions taken by our "support admins". These were, in no case, appropriate for a TF2 gambling site and we have removed said admins along with others that are not needed. We'll be taking extra time in screening our admins from this point forward and don't expect something like this to happen again.
As a side note, we're having issues with the withdraw part of the site which we'll be fixing over the next couple of days.
Thank you for your understanding,
Julian
