Why Are You Getting Fake Signups?

Fake signups come from various sources, and they can harm your business in multiple ways:
  • Fraudsters: In industries like fintech, bad actors often try to sign up with the intent to commit fraud, whether it's abusing financial services or exploiting loopholes in your system.
  • Pen Testers and Hackers: Some users aren’t looking to be customers—they’re testing your security or searching for vulnerabilities to exploit.
  • Disposable Email Addresses: Fake signups often use throwaway email addresses that disappear after one use. These users aren’t real leads, and they’re only here to abuse your service.
  • Free Email Accounts (Gmail, Yahoo, etc.): Abusers can use free email services to bypass your signup restrictions or remain anonymous while taking advantage of free trials.
  • Competitors: Competitors may sign up just to spy on your product, cluttering your system with irrelevant data.
  • Hidden Identities: Users who hide behind VPNs, proxies, or anonymizers can abuse your trials or bypass geographical restrictions.
