. Exchanges just use heavy KYC as a pathetic excuse to delay withdrawals and disable your account if they just decide you have be their monkey today and eat shit while filming it all to fulfil their KYC requirements.
Bolded quoted message is just for those exchange which arent that known or does have lots of complaints and issues where they do make use of that kind of situation to prohibit some users to comply and
get all of those funds that user have or simply confiscate or whatsoever in related to that.
Going back about enforcing KYC then expect it would really be on that path knowing that these platforms are regulated or following a set of rules but actually it isnt on the situation where you as a user would be tied up
that tight into your neck since you do have the options to take.
Just like on the example on where Binance do give out 2BTC/day withdrawal without KYC is already a generous take unless if you are a whale then that wouldnt be enough.
Any transactions that do correlate or connect with fiat then you would really need to go with the process.
