Ask HN: How do you manage registration spam?

I've been running digital marketing on a few projects and all seem to suffer from many "spam" signups.

I can only assume the main intent is to find exploits with email and billing systems but there's a long list of other nefarious activity that could be at play.

I've set up a custom tool to monitor and prevent suspicious signups (looking at email deliverability, light identity checks and some AI with tuned prompts). Captchas don't seem to cut it as abusers don't seem to be bots.

Is this a problem other people are facing and if so how do you manage it, if at all?
