Thanks for sharing, is the registration for XSS available?
In addition, delving into this case, I was able to talk to some people whose level of knowledge is colossal. And they shared information that sinbad was not confiscated by the authorities, saying that this was just a very well-developed trick to relieve tension. Which is quite logical... considering that chainalysis reported that after the closure of sinbad that YoMix's turnover increased 5 times. Secondly, this was the first time that a stub was placed in the site’s corporate style (some people appreciated LZ’s humor).
I tend to not agree with this, Sinbad.io(not .onion) was seized and registration data for Sinbad.io similar to what happened with Chipmixer + we have a screenshot from the @fyodnederland account

Back-End and mixer Bitcoins were not confiscated.

As it seemed, they were planning to create .onion sinbad link and turned into darket-Mixer but and after the signature campaign was included in the sanctions list, they used Yomix instead.
