PSA: It looks like mastodon.social has implemented hCAPTCHA on their signups yesterday.

So, if you have limited / suspended mastodon.social because of the spam issue, you may wish to reconsider this.

This will also likely mean that spammers will move to different instances (already seeing them targeting mastodon.world).

You may wish to consider implementing hCAPTCHA yourself to protect your own instance, and here is the relevant PR:

github.com/mastodon/mastodon/p…

The reason I'm suggesting this, is because if you are a small/medium instance with open registrations, and spammers find and abuse your instance, I imagine that other instances will limit/suspend your instance without hesitation, given how willing some were to limit/suspend the much larger mastodon.social.

But do note this comment on the PR:

“To give some context to people seeing this: this is an emergency feature backport from Glitch SOC to help mitigating an ongoing spam wave, this feature may not make it in a next release, or with significative changes.”

Edited to add: multiple people have rightly commented on the accessibility concerns with hCaptcha: hCaptcha is really really really bad for blind and visually impaired people.

Please have a look at this excellent reply for more details:
