To be honest, if you care about privacy you should actually only use well know gambling sites.
my point is to create awareness among the unknown users before they get into KYC drama.
ok, but your topic without proof is an attack on these sites and nobody will just take your word for it because you are a random account on bitcointalk that doesn't even have a history around so we don't even know you!
provide solid proof that these websites you listed here asked for documents regarding KYC and we will all stay away from them. don't provide any proof and we will ignore you.
