List of Casinos and Sportbooks to Avoid
You can use this topic as a reference for your blacklisted casinos. There is even 1 site which is listed on above thread as one of scam sites but it is listed on your site with 3 Stars. The site is bitstarz, it has bad reputation in this forum so you may consider to move it into your blacklist.
One more thing, you may visit duelbits and you may add it on your good casino list as it is a good site in my opinion. Not because I'm participating on their signature campaign but because I play on that site with my own money worth more than what I get from the campaign.
