We've detected suspicious users abusing our API

Kevin Sahin @KevinSahin

Today we found some suspicious sign-ups with strange email domain names.

In ScrapingBee API we offer 1000 free API calls on sign up, and those people are abusing this by registering multiple times. 😡

It seems those emails are not coming from traditional disposable email services so I wasn't able to find them on open databases on Github.

There are many things that could be done to solve this problem, like additional fields on Sign up, phone number, or requiring a Credit card ...

The problem is, most of these solutions would lower our conversion rate.

How do you solve this problem?
I've heard about two APIs to check the "reputation" and score an email address:

Any feedback about this?
