It's pretty irresponsible to host a service without understanding anything about it. I have yet to decide if we should encourage this, I'll get back to you

A lot of money can be made this way, don't get me wrong. Their incentives are clear. It's just that ... deploying code you don't understand is already bad, but deploying it onto infra you don't understand is outright negligient.

Can you alter the instructions to describe how to deploy to exe.dev manually? We can include a warning box near the end of the page which mentions that an idgaf-deployment via LLMs exists, and when people should/shouldn't use it.
