But often these screenshot evidences are nullified when the reputable casino counters the said screenshot so it is not wise to easily jump into conclusion without hearing the other party's story.
Most of these stories are found to be the complainant's fault. Being unable to login is possibly their internet's problem, or they forget their password and took long for them to get a new one. On not being able to withdraw also has something to do no how they are found out breaching terms and conditions but making some false accusation of the casino being a scam just to get sentiments from the reader pressuring the casino to give in to what they wanted.
I feel normal, and thinks that those who experienced difficulty possibly did some cheating or exploitation that triggers the casino to implement restrictions on their account. Being able to log in, play and withdraw is a normal thing when engaging with gambling site, so I do not think that there is a need to feel to be lucky if one is experiencing such normal stuff.
