Be aware that at least in the US, many people who graduated from university can get an .edu alumni forwarding address. I have a rather cool one. I got in early on and it’s just my first name. I don’t use it much though. In the early days the forwarding made it sometimes unreliable although I assume it’s better now. And the reality is my gmail address has been stable over a couple decades at this point and I don’t see that changing.
I give out my edu address to very few people in any case.
Thanks for the heads up. We're aware, but tbh are not that worried about it. If someone that has already graduated is keen to get a student discount, I'm happy to let them. They feel like they're beating the system, and we still get paid. Luckily we're not running a business where the educational discount users are some sort of loss-leading onramp that we expect to make money on once they graduate – they're still profitable even at 50% off.
Currently we actually require manual verification (sending in a student ID to our Intercom) if you didn't sign up with a educational email, and I'm deliberately overlooking the proofs that are clearly invalid. I barely even glance at them. The other day day someone sent me a student ID that was 4 years expired and I just applied the discount and moved on with my day haha. If you send me a PDF called "student_id.pdf" I'll probably give you the student discount. That's part of the reason we're adding this system – we've gotten so lazy that requiring people to go the email verification route will probably be a stricter improvement on the status quo if most users go that route.
In general I think that’s a good attitude. A lot of people who work the system for a student discount probably wouldn’t have signed up at full price anyway.
