The site looks good and legit at first but it seems that there's no much evidence for its claims such as 'provably fair' gambling and there's no mention of KYC either, or did I miss it all?
Maximum site does not require KYC if they do not think you are trying to scam or if they do not think there is anything which is being used by scammer.
doesn't make much sense - it is either written in TOS or not
if KYC is not mentioned in their TOS , means that they are not going to enforce it - simple as that
in some cases , even provably fair sites put KYC in their TOS - example : Stake and Primedice
but this is more due to the fact that there might be a valid reason to check the identity , i.e. stolen or tainted coins and so on
doesn't mean that they ask you for KYC even if you win 10-20 btc
unlike your regular casino where you can be asked for KYC after every step of you trying to get the money out of them
