No, it makes you an accessory because you are mixing your traffic with criminals’ to help hide all of your activity. Everyone trying to hide criminal activity needs to use a mixer but only a small percentage of other users are going to pay for an optional service so the odds are worse that you’re more likely to attract attention to your transactions, too, just like you would if you were known to take home large quantities of cash from a mob-owned casino, too. Maybe you’re just a really good poker player but it’s more likely to make law enforcement curious than if you don’t.
