As far as awareness, someone going to have to keep an active scam casinos thread(there is 1 I'd just have to search to find it) or keep bumping this thread every few weeks. Both scenarios don't really mean that a reader or potential player would open either thread and read though.
I don't think there is a need for active scam casino threads since it's pretty easy to find these scam site threads within this forum with a simple google search if customers are willing to do their research in the first place.
For example, 1xbit abandoned their operations within this forum a long time ago, but their scam discussions within this forum easily appear on the first page of google search.
