I have never even heard of any of the publicly available blockchain forensics databases, or reviewed any of the ample examples of reporting and analysis on the subject.

That's not what I asked about and you know it.

I asked how you know about vendor money laundering techniques, which you failed to provide a source for.

it’s extremely well covered

If that's the case, then you should be able to easily provide a source instead of flailing around like you're doing now.

so stop being a lazy twat and look for yourself.

You made the claim. You provide the source or you admit you're making stuff up.
