Sorry but the proposal is egregious, considering your website's access far falls short of a DDoS attack against it. You voluntarily host it on the public web. Pay-for-access proposals have existed for decades, and there is a reason they never go anywhere.

Even a $5 VM I have has an included quota of at least 1TB egress data per month, and it can handle 9,540,534 requests in a day if not less. A Rust server can handle a lot more. In practice, my egress quota is larger by virtue of having a couple of more nodes.

If you actually cared, you would use something cheaper then AWS, ideally with zstandard compression, and a CPU efficient service that doesn't buckle under a moderate load.
