+ 1 . @davwheat @dsevillamartin (tagging you because you have the most recent commits on the repo) can you have a look ? There's a pending PR #51 for this.

PR #51 is an important bugfix. Currently users are complaining that they cannot reset their passwords and get a red "The g-recaptcha-response field is required.' modal. We cannot really do without this plugin as we've had issues with bots creating accounts before.
Is this plugin still maintained?

Use the cloudflare turnstile plugin, that one works.

Fwiw, I have both turnstile and recaptcha enabled and yet get in excess of 10 bot posts per day alongside several more bot registration and honestly I am pretty fed up. Anyone else having similar issues? Anyone in the position of making comparisons with bot detection on other forum software (e.g.: Discourse)?

You mean the Blomstra one? https://discuss.flarum.org/d/31790-blomstra-turnstile
That one is unfortunately officially abandoned. I'll check it out but I think it's quite problematic that the only captcha solutions for Flarum have no maintainers...

Actually nevermind, it is showing up but not working at all. You can just login without solving the captcha (if you want to test: Use the tor browser, it should require manual intervention or just fail straight away).

Given that's not clear from a user perspective, and the plugin pretends to "work" that means that the blomsta plugin is outright dangerous by now and should be archived/removed.

Turnstile is broken and not maintained.
