-One thing for sure is that an ANN thread is a good way to expose scam casinos or casinos with low reputations, and if a newbie will take time to research and check various channels for information about a casino there will be no way their will not notice the activities of those casinos.
Exactly, but almost all victims are lazy sloths who don't want to spend extra time researching sites which is why they end up getting scammed and whine like crazy later on. It hardly takes a couple of minutes thanks to Google, Bitcointalk etc.
but I saw that only one of them was known to me (BitStarz) and all the others were unknown. That is why I'm confused about the OP's list and I don't think it's reliable.
Correct. Bitstarz has some scam accusations against them which they never resolved which automatically implies that OP's list is not trustworthy.
