Examples provided as technical examples, strong feelings are out of scope for this thread.

As someone who operates a large non-profit public data driven website, I have some VERY strong feelings about scrapers. We looked into various commercial solutions (Datadome, HUMAN) and based on our traffic estimates from logs we'd be looking at at least 250k/yr for bot mitigation. Anubis is offering a temporary reprieve, but after reading the recent kernel.org article [0] it's increasingly clear that this is a temporary bandaid.

The cheapest solution is to require a login and rate limit by API key. I also have strong feelings about the tragedy of the commons.
