@Synchronice,

Other mixers may be very willing to work with "bad money" and not think twice or have connection to states like NK (even if unconfirmed). So that's why and how they succeed. Judging by the number of refunds we issued with the help of minerjones it was basically only the signature participants who had funds on there.

Casinos are easier, they just need to be seen and players will eventually come. I'm not even sure that the pool of users on bitcointalk who are in need of or actively use mixers is particularly high.
