Ask HN: How Do You Handle "Power-Users" on an Unlimited Plan?

I've been running into a bit of a challenge lately. Some users on our Unlimited plan are using it way more than the average user, about 100 times more! This is starting to cut into our margins, and we're not quite sure how to handle it.

Has anyone else dealt with this? How did you approach the situation? Would love to hear your thoughts and experiences!
