The proof of work stuff feels so cryptocurrency adjacent that I've been looking at other tools for my own thing, but I've seen Anubis on other websites and it seems to do a good job.
Also: Anubis does not mine cryptocurrency. Proof of work is easy to validate on the server and economically scales poorly in the wild for abusive scrapers.
I’m glad there’s no cryptocurrency involved (was never a concern) but I worry about the optics of something so closely associated.
(I appreciate your commenting on this. I know the project recently blew up in popularity. Keep up the great work)
