Happy to help, what exactly should be explained further? Maybe the below already helps. FYI, my posts only contain publicly available information that anyone can find on the open Internet, if interested. I'm just trying to help, by summarizing it for interested folks. It's a very fascinating space to watch. Just for the record, I'm not encouraging anyone to break any laws. I'm sharing facts, that's it.
The best way to learn which companies freeze assets is probably via Twitter search.
When people have their assets frozen after mixing/coinjoining their cryptoassets, they often complain about that on Twitter (tagging the respective service that froze their assets). Most people are not breaking any laws, they just want some financial privacy. Thus, they are naturally very annoyed if their funds get frozen and it takes them weeks & experiencing massive privacy invasions to get their money back.
With a bit of searching on Twitter, one can find services that have frozen funds in the past.
PS: Some exchanges have frozen remaining user funds when customers used above technologies AFTER withdrawing some of their funds, even when the coinjoin happened 6 months later.
This was just a warning to make people aware of the massive overreach that's happening. There have been some infuriating examples where users had withdrawn some of their funds from custodial exchanges (to an unhosted wallet), kept their funds idle for 6-12 months, and then obfuscated the trail via a privacy-preserving technology (in this case coinjoin). Some exchanges work with service providers to monitor for such behavior and freeze all funds that are still left on the exchange.
This is obviously totally unacceptable. People are not committing any crimes, they just don't want everyone to know what they do with their money and how much they possess.
Does that help?
