"It's not a platform's fault for blasting lots of reports which they reckon are very unlikely to be child porn and are never going to be followed up on." (paraphrased)
Actually, it is. Accusing someone of being a child predator (or whatever it is someone is thinking) is an egregious violation of #privacy and part of why #chatcontrol is so notorious.
And if we're gonna admit they're never going to be followed up on, then surely it should be a no-brainer to prune it back to protect people's privacy? If it takes legislation to do this, then so be it.
