On this case, Jambler actually do the exact opposite of mixers in the sense of laundering money; receiving tainted money and sending them all clean and shiny.
Mixers do two things. Receive money (be it tainted or not) and send money, to break the link. Jambler's partners use the Jambler API to do that. You could argue that every other mixer receives "tainted" and sends "clean" coins, just as well.
Am I the only reading that they perform blockchain analysis it to prevent scamming their own platform?
This stage makes it possible to terminate attempts of unfair investors to use an investment admittance as a mixer in order to clear their money and gain profit at the same time.
Examining coins to check that the investor doesn't try to cheat the system, and examining coins to avoid receiving "tainted" coins are two different things.
