Reminds me a little of RECAP (https://free.law/recap), an automated scraper/saver/sharer for PACER (the US court electronic records system).
Obviously the content is very different, but the technology is basically doing what you’re talking about, minus anonymizing the data.
I use RECAP constantly and try to always upload everything I grab from PACER.
I think this administration finally passed a law to make PACER free, which is good.
