Best Captcha to Prevent Bots on Your Forum

[Bawse]

What captcha service do you use to prevent bots from joining your forum?

I've been using Google Cloudflare, but I noticed lately some spam accounts have been getting through, and I removed them.

I used to use Google, but it became less effective. So far Cloudflare Turnstyle has blocked everything except the random human spammer from time to time.

Thanks. This helps. I've had spammers getting through lately and posting a intro thread, and nothing else. I just switched to Key Captcha. I hope it's better.

We've had the same, along with some other forums I've noticed. They're always using a different username, but the same introduction content is posted. We've even had different accounts using the same intro post on one forum. Doubt they're bots, most likely just stupid human spammers.

We also use Turnstile here.
