E-mail and forum are completely under your control, there is no way to complain directly without you.
How did you know that email and forum (what forum) are under control of TheQuin? What forum is you are talking about? I guess it is forum account but on what forum?
About this forum, it is one of media you can communicate with FreeBitco.in but if you want to make support request, it should be done on the FreeBitco.in website.
I am pretty sure wetsuit did a good security check on TheQuin's account before he decided to employ him.
TheQuin works for FreeBitco.in many years and before the start of their signature campaign on the forum. Even the campaign is a long one, two years.
If TheQuin works for the casino long like that (more than two years), he can be trusted.
He controls 2 threads on the forum. Even if the offended user creates any other thread on the forum, he immediately blocks/deletes it, since he has familiar forum moderators. He also answers support letters, he also deletes accounts, he can also change the password. Read the stories about how some lost the 2-fa code, he replied that they would never be able to restore their account. Guess what will happen to the balances of these accounts? Will Wetsuit know about this?
