@aral : regardless of which chat app you use (if even any): if you want to help protect children from being (sexually) abused, wake up everyone who thinks that Chatcontrol will solve that problem.

On the contrary, it will make things worse: not a single abused child will be found while the number of (police) officers, who chase actual abusers of children, will decrease. More info via https://infosec.exchange/@ErikvanStraten/113090311124341304.

There are a zillion of other reasons why Chatcontrol won't save children but will cause havoc: it is *hard* to *re-detect* known CSAM video's (https://safer.io/resources/video-hashing-challenges/) while it is impossible to reliably detect abuse of children in live streams.

I am going to share this as I think there is a much wider point to make. Last year, I studied the #Immensa #Dantelabs #COVID19 testing scandal.

A large #PCR lab basically produced tons of #FalseNegatives -- see my thread from last year:

Today the #Inquiry results came out. Wrong equipment settings were to blame. This is what produced the #FalseNegatives.

More importantly, there is now an #Epidemiology paper with *13*
