What many people don't know is that mixers are given the room to run on one condition, keeping users data aside just in case, isn't this why users are trusting mixers anyways? You can't get away with crime using mixers.
Im sorry I've to break this bad news to everyone, someone (a dev to be precise) tipped me off about this and that's why I don't see anything wrong with users using mixers but if your aim is to do some crime, not just any crime, a significant one, you will be caught.
We have so many gullible people among us in crypto space today, crime is better committed offline than online, there is no way you can hide completely, you can have the time to break into a server and install your infected code and get out, but it doesn't end there, you can't outsmart the government, they have all the tools and access to bring you to justice.
