Mixers are now under attack by American authorities, with Tornado Cash and Blender being their first big victims.
Moving on my opinion about this (because they wouldn't be relevant at all), do you know any other reliable mixing platforms?

They have been always under attack, not sure if you are already in this community when this happened:
