Everyone's personal responsibility for reading the ToS Here, if someone thinks it is a waste of time or starts gambling without getting too excited and goes against the ToS and faces any problem, he has to take responsibility for himself.
I think that the TOS is one of the most important pages in an online casino. It is usually a long read but it tells the potential clients everything about the casino. Once you have built a habit of reading the TOS before registration, you will be able to know a casino that is genuine or one that just copied and pasted the TOS of another online casino as their own.
In short to avoid calling an online casino a scam, read their TOS in addition to other rules and criterias before going on.
