This is exatly the problem with pseudoanonimity. The moment you start tracking actions with unique identifiers, even if those identifers are not connected to real names initially, you're opening a big box of privacy no-nos.

You just need one instance where you can connect a pseudonymous identifier to a real person, and boom, you have the whole history and future right there.

not interested in that but yeah its there

Also other leaks that had names and addresses but not amounts.
