Question
People create new accounts with temp emails to get the free credits again
My app gives 10 free AI credits at signup. I see the same person (same writing style, same kind of requests) with like 15 accounts using 10minutemail type addresses. Each account costs me real API money. How do other apps stop this without making signup annoying?
What I’ve tried
Thought about blocking a list of disposable email domains but there are thousands and new ones daily.
Following, same problem with my image generator.
