So I decided to take a deeper look into it, and it turned out that not only does Anubis have a fragilely designed PoW (Native accel + Concurrent solver can solve it within 100ms), it also tends not to use PoW by default.
As a PoC, I've created a solver in Python, which can be used like:
I don't really like to think this way, but it made me doubt whether it's really possible to make something, especially FOSS ones, that can stop crawlers or similar stuff. Anubis, at least, doesn't seem "right" to me.
