actually it is not a word force because it is already written in the TOS about KYC verification , though it may not implemented strictly yet the chance of being asked is always there so be ready in giving yours before even considering to deposit and play.
like what mostly says here, if you don't wanna go through KYC then play somewhere else that does not ask for KYC as there are still plenty out there .
the best thing is deal in casino that you feel contented.
