It nowhere says "money laundering" and "taint". AML services always tell you that they do blockchain analysis to prevent receiving "tainted" coins or to fight money laundering. It is quite obvious that you can launder bitcoin through the partners of Jambler, and perhaps it is their best selling point one could argue.

The closest wording to "taint" is "cryptocurrency of questionable origin", which I agree that it's vague, but it doesn't necessarily mean "tainted" with the accepted sense of the term.
