Unfortunately, one more mixer is out of business. They may have been the youngest and have not yet acquired a user base, but they are certainly entering a negative trend of decreasing privacy service options.
Why do you still have Tumbler and Unijoin listed when they are not available for some time?
It could be someone's (ie the operator's) personal account or something?
I don't know but it's stranger that someone continued to post, unless this is just AI generated content.
All other accounts Unijoin used are not active anymore, but scammers could always create phishing pages, so better be alert.
