This won't help you if they do an exit scam.
Unfortunately scammers know that and they abuse this way of thinking. There were many casinos that scammed people. I remember some of them back in 2014 and 2015 were launching big signature campaigns trying to be the biggest ones on bitcointalk. 1xbit is considered a scam and it has a presence on the forum, running a campaign.
Bottom line is, you shouldn't think in these black or white terms. There can be legit casinos with no threads or campaigns on bitcointalk and the other way round.
