I’ve never received an email response from this group (6 casinos in all I think), and I pulled their links down months ago.
However, I still occasionally get paid by them, and I’ve actually had some decent amounts a couple of times. It seems like this group was set on auto-pilot long ago, and there’s actually nobody home. Somebody’s doing payment processing, but that’s the only sign I’ve ever seen that there was anybody at all behind those email addresses.
