You should be that careful on trying out to believe on what these newbie accounts been telling. If you do try to check out reputations board or scam accusations board then you could be able to read up tons of complaints by these newbie accounts on which most of the time it do ends up on having that trolling or false negative on which its not that new anymore that these are just that trying out to messed up on someones platforms reputation via creating some fake issues on which they dont even have that solid proofs about on what they do claim and trying out to spread up those issues on different threads such as this one and just that making it look bad. Best casinos usually be that found on this board alone with having those ANN threads then you can check it out on which one will be that goes inside with your criteria.
As a rule of thumb, I would never blindly trust any newbie praising about any gambling site or accusing any gambling casino for unfair play or scam. Also, I will avoid the casino reviews site as those are the ones usually made to promote the author's referral links.
The best way to know about any gambling site is to visit its ANN thread and read the last three to four pages of the thread. If the majority of the people are discussing about the casino's and not complaining about it, you're good to assume that the casino is good and trusty worthy to gamble.
If you read majority of the posts complaining about the site, then you should be very careful playing at that casino as there would be 80% chance that you could face similar issues while gambling there.
