I also don't get the comments on the linked social site. IIUC the users posting there are somehow involved with kernel work, right? So they should know a thing or two about technical stuff? How / why are they so convinced that the big bad AI baddies are scraping them, and not some miss-configured thing that someone or another built? Is this their first time? Again, there's nothing there that hasn't been indexed dozens of times already. And... sorry to say it, but neither newsletters nor the 1-3 comments on each article are exactly "prime data" for any kind of training.
These people have gone full tinfoil hat and spewing hate isn't doing them any favours.
