Hmm, I am divided on the human verification.

It might work splendidly.

However, if someone dislikes you for personal reasons then what would stop them from reporting you as a bot. There is a risk of gatekeeping involved, although it is hard to measure how much of a risk it is.

Yet, if we don't have a human verification system, then we are at risk of algorithms doing the sorting work and mislabeling humans as bots or vice versa.

So I guess we don't have much choice.

Better to have humans identifying humans than algorithms doing it badly.
