Obviously we all know scammers and criminals are no good, but if you call your service pro-privacy, then you cannot selectively offer privacy by hiring a blockchain analysis company to spy on people's utxo's and tell you if they should be allowed to swap their coins or not, eXch doesn't require kyc for a swap, you just swap your coins instantly after you make a deposit, they can't know how and where the coins came from, because they don't spy on you.

eXch also log ip addeesses and if you don't believe that, then they are also tor-friendly, so you can use their onion link and connect to their service over tor to ensure your privacy, in that case, there is no way they can report back to LE when they are retrospectively required to provide info about a certain tx. Op there are already enough centralized exchanges and services doing what you ask, you don't want all the remaining privacy tools and services to become honeypots for the government, do you?
