Organization to keep track of wrongfully obtained bitcoins I am curious whether there are any organizations that are actively trying to monitor bitcoins from illegal sources.
I understand that 'when done properly' you can make bitcoins practically untraceable, but I have just witnessed a rather amateuristic attack where people were suggested to transfer funds to
3EaRJ5p172iLYJKH8YYnPYFw9pKgxYg1sj and I wonder if anyone is trying to do something about these cases.
Just one partial solution I could think of would be to alert exchanges or vendors when the bitcoins are traced to them, so they can hold the funds untill the situation has been cleared up.
I am not asking whether my proposed solution makes sense, but I do ask  if there is any organization/solution that structurally tries to make life difficult for bitcoin criminals

So far I have seen a lot of answers explaining you cannot catch all criminals, but I would be surprised if we cannot even catch some.
I also found a reference to nomoreransom.org but ultimately that just referred me to the local authorities, which makes me doubt there is a structured approach behind this.
There are companies such as Chainalysis (no affiliation) and Elliptic (also no affiliation) that attempt to perform such analysis and group addresses into clusters based on the entity (exchange, scam, unknown, mining pool, gambling, payment services, etc.) that is believed to control them.

They offer their analysis to exchanges, governments, merchants, etc. for a price, as any other business.
