It's true to read rules of events like free spins before joining it. If you see rules are not attractively good enough or contains some requirements you don't like because you see it violates your privacy, simply ignore those events.
Right if you are not comfortable with the rules then don't participate at all in them because after that you won't have any excuses and we are not forced to do anything.Like for KYC if we are comfortable with it we can proceed further and if not then we have choices also so choose accordingly.
people always complain about KYC even though if they want they can just choose another casino that maintains their privacy, after all there is no compulsion to play at a casino that asks for KYC, everyone has a choice so before playing don't continue if you really don't like the existing rules including KYC .
It must be realized, basically this casino does not require KYC to play unless they follow or do something vulnerable to KYC like a deposit and ask for withdrawal without wager or shoot a big win or even like my last case obviously it requires KYC, in this case nothing can be blamed because that is indeed the rules that apply in almost all casinos especially casinos that have a license. If we prefer to play online casinos then we must be prepared with risks like this no one can ignore it, therefore we must read the rules that apply in each casino before creating an account or if we don't like it, it's better to play in real casinos.
