Yes it's P2P but still a "widely known" trading platform,
regulators wont tolerate any crypto in their sights that has the potential to become a hidden sub-black-market trading ground
3rd party trading service providers that requires KYC verification even before this KYC "issue" became a Bitcoin-users' issue,
and I didn't have any problem with that (In my case).
If you wanted to trade Peer-to-peer anonymously, use other "methods".
