1) What problems have you recently encountered regarding online gambling? (or what have you disliked recently?)
Casinos asking for more documents to verify after a win. When casinos use the right to ask for extra verification documents to inquire about some information I don't want to expose, it becomes very annoying. I prefer the casino to state all the documents they require in the terms of service instead of coming up with more KYC verification after a win.
There must be a reason if the casinos asks their users to do the advanced KYC, perhaps because the user made a big withdrawal or bet on a suspicious/rigged match (sports), or suspected of multi-accounting, bonus abuse, etc.
So it would not be correct to say that all casinos will always make it difficult for their players when making withdrawals with advanced KYC stages after they win something.
And yes its a bit annoying when we are asked for additional documents for the advanced KYC, but like it or not - it has to be done because we as players have agreed to their T&C when signing up on their platforms.
