I'm glad that there's now a thread dedicated to this topic. I've been writing for years that a list of casinos where a person should not play is no less important than the list of reputable casinos, and now there's finally a person that is working on it. You might find this thread useful for your list because there are casinos whose owners have negative flags here as well: https://bitcointalk.org/index.php?topic=5154971.0. I think Betking.io deserves a spot on this list, but then again it seems that the casino's closed, so maybe not. I also wanted to ask about Nitrogensports. I know it's pretty popular, and I personally did not have any problems with them or their manager, but there've been some accusations over the years (the trust feedback mentions it). Maybe casinos on the list deserve gradation? Like, black list, red list, orange list based on how certain it is that the casino is bad.
