As someone who has been in the messaging industry for more than a decade, it sounds naive to think that the litmus test for whether Apple will ban you is whether your traffic qualifies as spam. There is a long history of people trying to get around A2P spam filters / fees / traffic limits / onboarding / KYB requirements by running business messaging on P2P pipes, like you are doing. Some of it has been successful (see Twilio in the early days) but the industry has gotten a lot more sophisticated around this stuff and is not going to be receptive to your approach, which to me resembles the SIM farms that are a scourge when it comes to consumer fraud and abuse.

> Apple wouldn't ban us since we're not doing anything that would qualify as spam or abuse

Hmm, I wouldn't be so certain about that. Apple can ban you for whatever they like.

…so you have a Mac mini farm

> Apple wouldn't ban us...

To me this screams you haven't talked to Apple. Given how macabre they were towards Beeper Mini, I almost expect the same treatment for Chert.

Nonetheless, best of luck if you can pull it off.

Did the YC interviewers ask you about this risk?

Did they ask you about a bigger market you can move into?

There's no way this foothold will last. You're going to get massacred.

Apple WILL ban you. You're not in some capricious walled garden. You're breaking and entering, and they'll destroy you.

There is nothing of value to build here. You should take the rest of the day off, then tomorrow, pivot entirely.

The folks here are trying to save you n years of hard work and wasted effort. Please listen. You're lucky to have a YC check. Apply it somewhere else, to some other problem. Preferably not in someone else's garden, and especially not in one where they shoot to kill.
