How do you protect your SaaS signups from bots and fake accounts?

Hi everyone! 👋

I’ve been experimenting with ways to reduce fake signups and bot accounts in SaaS apps. Some approaches that have worked for me include:

• Detecting disposable or temporary emails

• Identifying VoIP or invalid phone numbers

• Checking IP reputation and datacenter usage

• Assigning a risk score to new signups to help prioritize real users

I recently built a simple API to experiment with these techniques and would love feedback from other devs if you’re curious.
