Scrapers scrape all sorts of nonsense, notably every possible git diff from git hosts. They clearly aren't concerned with rationality.

Scrapers scrape every link they can find.

The git host example is probably the one which Anubis is the dumbest defense for: the main reason to have those links is for easy machine interaction. So that's dead when you implement it.

So why even host the links? It's a git repo: send them a local got client and let them clone the repo in browser or something.
