Drive-by Account Creation driving up MAU

Looking for advice from anyone who has a similar problem.

Auth0 considers anyone who creates an account or logs in a MAU.

Our application requires both Free Trial users and Subscribers to have a card on file. Since earlier this year, we’ve started to see a huge influx of passerby account creation driven by recommendations from ChatGPT – specifically, these users passively create an account, hit our pricing page, and then bail/leave.

This has resulted in an explosion of “no/low value” accounts increasing our Auth0 MAU – nearly 15x over what we actually see even ever hit the application itself.

We aren’t incredibly interested in anti-growth hacks that would add friction to registration and hurt our actual subscriber volume .

Has anyone run into this problem? How have you navigated it?
