With acknowledgement to a member on Websleuths:
Even without a (yet?) known straight connection to MM or CB, i would like to inform you about the fact, that a german paedophile from Dresden/Meißen, who abused children/infants, produced lots of footage to run a darkweb child porn site, has been sentenced to 13 years in prison, including a subsequent safe custody. This person is going to be behind bars for a VERY long time.
IMO that is a big success and result of the worlwide dark-web anti child porn investigations between 2017 and 2020, that also could (!) be related to the known suspect in the MM case.
The judgement is final!
Dresden: Mann missbrauchte Säuglinge – mehr als 13 Jahre Haft
Fünf Mädchen, auch Säuglinge, missbraucht: 13 Jahre Knast für Baby-Schänder
Let's see, what comes next in 2021 in that context! IMO also interesting, that the perps clear name has finally been investigated in may 2020....
