As a link between Blender and Sinbad had already been established in the Wired article, it was merely a question of time before it was seized and the people behind it arrested. I created a thread in May 2023 while Sinbad was being promoted in the forum: After Chipmixer, Is Sinbad.io Next To Be Shutdown?

It should never have been allowed to be promoted inside the forum after it was public information that they were accused of money laundering. No decent campaign manager would have promoted them if they were tainted with serious criminal accusations. I believe that was one instance theymos probably should have intervened and banned them from offering their service via the forum.

As for the present, Sinbad was the last straw and it is clear mixers will not be allowed to return because the risk of people believing this forum and mixers are synonymous is real. To many people mixers equates to illegal activity and for that reason alone there is no reason to lift the ban.
