I do understand big miners get nervous. Their magnitude drops and they can't do anything about it but to try and blame someone else.
Actually, we found out about this months ago and did nothing, mainly due to CM being very opposed to saying anything publicly. It was several big discussions in the Slack channel between many users that made us decide to say something. I personally do not care for mag - check my project selection if you don't believe me (Einstein@home on all GPUs - literally the least efficient).
I don't recall any such communications regarding your allegations against CE.
I am indeed opposed to public slander & doxing of individuals of whom you suspect are committing serious large scale computer crime (running a botnet will get you life in jail).
The best course of action is to contact the BOINC projects direclty, specifically their cyber security divisions - Oxford, IBM, LHC, they all have dedicated teams whom can investigate such claims with greater access to volunteer data.
If not BOINC projects then you should have contacted the authorities with the information you believe you have. Posting a smear piece like this without concrete evidence is likely going to get you sued by CE for public defamation/slander.
