Ask HN: Top of Funnel Fraud Solutions

Hey all, I am looking for a little advice on a lightweight SaaS offering to protect my top-of-funnel user sign-ups coming from my website. Recently, we’ve been getting more and more bad signups with fake email, etc. It could be a coincidence, but it seems to coincide with the recent wave of ChatGPT (not sure if relevant - maybe the recent advancements with AutoGPT..?).

I was trying to find something that I could put in front of my user sign-up flows to see if I could weed them out more (save me money emailing, advertising, trying to convert, etc) and came across FullContact’s Verify products. Their “match” offering, accepts user provided input, and tells me if the sign up information looks suspicious or not. So far seems to be providing decent results in recommending when to introduce some friction vs not.

Anyway, my trial is ending next week and I was curious if anyone has experience working with FullContact or this product? Here are the relevant links if you’re curious. Appreciate the input in advance.
