It is inevitable that most if not all mixers will be used for (or will be attempted to be used by criminals for) nefarious purposes but when headlines such as "The world’s most prolific crypto thieves have used Sinbad.io to launder tens of millions" are associated with a brand it means their days are numbered.

I found this article in Wired.com interesting on several levels such as the creator of sinbad.io who wants to be known as Mehdi named the mixer Sinbad after the fictional sailor that travelled far by sea. In the interview Mehdi seemed to comment on almost everything that was being discussed but when asked if Sinbad was a new version of (the now defunct Bitcoin mixer) Blender, he refused to comment.

"Elliptic" is a crypto tracing company and they have suggested $22 million moved from Blender to Sinbad in the very early days after Sinbad was created therefore that doubles the reasons why it will probably be the next mixer to be shut down sooner rather than later.

Sinbad,io probably does not have too much time before various law enforcement agencies get together to organise the shutdown of their website and try to arrest the owner/operator on money laundering charges. If criminal activity as taken place on an industrial scale and almost zero protocols were put in place to either reduce, minimise or eliminate the risk of illegal activity by the owner/operator they will end up facing serious criminal charges.
