Did you read that as 2023 instead of 2022? Otherwise, it doesn't make sense.
One thing he got right though, they do share a very similar visual style. That guy got arrested year ago though so it doesn't seem likely its the same person behind it.
If you check his very first post onb bitcointalk, you will notice that he started talking about his new mixing service on March 9th, 6 days before CM was seized. Did he maybe knew that CM will be gone in a matter of days and he already started preparations? Or maybe this was just a coincidence.
Then again, it doesn't seem to me a smart thing to do to start a new mixing service when you are on the run and trying to hide.
