Some people complain that Bitcoins are anonymous. However, Bitcoin users can be traced back to the webmaster.
The bitcoin payment gateways from Bitpay, Coinbase or Gourl mention a list of useful information in their code that can be used to track the recipient of the money. For example in the Gourl code, there is a token key that helps to identify the bitcoin beneficiary. For example, let’s imagine that a blogger writes several articles to criticize the totalitarian regime of his country. He uses a bitpay , gourl or a coinbase payment gateway to monetize his website.
GOurl.io, case study – Information collected:
Many pieces of information are collected from the use of a website using Gourl.io which will be the ground to allow tracking of a webmaster and its buyers.

Webmasters can be traceable thks to companies:
Authorities and people who want to find this webmaster just have to look into the source of the payment gateway to gather information. Once they know it is a coinbase, bitpay, gourl account, they can try getting the identity of this person by contacting coinbase, bitpay, gourl.
If you think that those companies will not cooperate to disclose the information about one of their users, it is just your assumption. Whether coinbase is located in the USA or somewhere else, it does not make any difference. They can disclose the details of their users to third parties.
Interpol blue notices:
Then, if a law enforcement authority decides to prosecute the webmaster and after discovering that the payment gateway company isn’t located in the country, they will contact Interpol to issue a blue notice. This goal is “to locate, identify or obtain information on a person of interest in a criminal investigation.” The blue notice is then received by a judge in the jurisdiction of the payment gateway company and they can force the payment gateway company to disclose information about the payment gateway user. It is theoretical. I don’t know if the receiving jurisdiction would accept to comply if the reason does not exist in the local law. Don’t forget that crimes are subjective. In some countries, it is a crime to be gay or criticize the leader of the country.
When people complain about how anonymous bitcoins are, they should take into account the actual system. Few people accept manual bitcoin payments which are really anonymous.
