I just came across this article which for people who are into self hosting can take a look and participate. It’s basically a tool that generating never ending web pages with non sense that load slow (but not too slow the AI tools move on) to slow down and thus cost them more to scrape the internet if enough people are doing it. You can also hide it in a way that legit user would never see this on your site:

Pretty sure this is what they scrape from your device if you install their app. I dont know how else they would get access to contacts and location and stuff. So yeah you can just run it on a virtual android device and feed it garbage data, but i assume the app or their backend will detect that and throw out your data.
