For scrapers that not just implementing HTTP, but are trying to extract zip files, you can possibly drive them insane with zip quines: https://github.com/ruvmello/zip-quine-generator or otherwise compressed files that contain themselves at some level of nesting, possibly with other data so that they recursively expand to an unbounded (“infinite”) size.
I seed, but I’m behind a NAT I don’t control without port forwarding, so I’m not a good seed.
Maybe I will do the seedbox VPS thing… after I get employed again.
