You're wrong.
Such companies track more than what you may think and not only to help an individual ripped off.
It's called data mining. They collect millions stuff.
Big companies like Bitstamp , etoro, and other CEXs are using it. So what do you think they're doing. CEXs provide them a lot of information about their customers trading on their platform.
It's not so different than a data broker.
data mining is such a powerfull industry, people do not realize what can be done with it... against them...
I agree with you and truly those companies can track a lot of things that we can't even imagine. They have internal links with many of the centralized bodies and large companies also provide details to them because they may get incentivize later on when cases are solved. Most of the Centralized exchanges willingly share data of the customers with them when any of the hacked coins are transferred into the wallets of those exchanges. That's also a way for them to gather data about the criminals who have committed the crime.
But, I still believe that sometimes the innocent ones can be caught due to the fraud of someone else. The criminals can sell those coins privately to the victims and some less-knowledgeable victims can purchase those coins for cheaper and send them their exchange's hot wallet address to receive to coins. Although those victims are innocent but those companies don't really care much about their innocence and action against them to show off their tracing skills. They may
Those type of companies are known for link building with other companies and thus centralized exchanges and all those other companies willingly provide information about customers and users to the companies like Chainalysis. I may be wrong but I think that governmental agencies also help those companies privately because those type of tracing companies can help to find the criminals and later on those agencies may seize the stolen coins from the victims.
Well, we really don't know their methods in details and they will never share their research details in public, and that's why I also believe that their data gathering can go wrong sometimes and innocent people may face wrong allegations because of the wrong practices of the companies like that. Sometimes they are so concerned about data mining that they forget that innocent people can also face tough times because of the mastermind criminals. Some criminals take ID card and other details of the innocent people and may register face accounts on their name and complete the KYC verification of the sites. In that case they will consider the victim as responsible for the crime not the mastermind criminals who used those innocents victims details to save himself from the crime that he has done.
