We spend lots of time finding trustworthy online casinos for players. When we blacklist a site, we are advising players to avoid the casino. Our “Negative Casino Reviews” section above has good examples. We blacklist a casino if it has a pattern of denied payouts, slow payouts, or poor customer service. We do not consider one disgruntled customer enough reason to blacklist a casino. If a pattern emerges through frequent user complaints, we investigate the red flags and blacklist a site if it’s warranted.
