Betharbor Casino: who licenses it and how safe is it

Starting with the licence, because that's the first thing I check before putting any money into a casino. With Betharbor Casino I honestly don't know who licenses it, and for me that decides whether I'd even bother registering. A regulator behind the site tells me who I can complain to if a withdrawal gets stuck.

The site itself works fine and looks clean enough, but a nice design says nothing about how a casino treats players when it's time to cash out. I'd rather hear from people who actually know the details than guess.

Does anyone here know which authority stands behind Betharbor, and have you checked it yourself? And if you've played there, how did verification and your first payout go?
