Well theymos added jambler to the mix. So likely we need it to stay open in case more is added to ban mix.
Fun fact, I made a list of Bitcoin mixers (outside Bitcointalk) where it is possible to compare each mixer, the features they offer, and the service fee... But I can't include Jambler as a mixer in that comparison table, because it doesn't have any of those parameters.

With The activation of new federal laws in the USA 🇺🇸 theymos will need to step carefully.
Bitcointalk has been banned in Russia, but who cares.
Maybe it's time to think about moving the forum to a friendlier zone until the new limitations come.
