30GB a month isn't too terrible? I guess it depends - for example my provider includes 10TB egress per month, so 30gb would be negligible if it's static content. I'm not sure what others do, but I often click on the links that the agents pull up as sources so the websites do get more discoverable.
What really sucks is e.g. Gemini that pulls images without being able to go to the source (unless it changed recently.)
Edit: I didn't read "logs"
1GB of logs, not content
The issue is that a dynamic site that can serve the traffic that generates 10MB of logs a week might be very performant on the smallest and cheapest of virtual servers, but one that generated a GB daily might find itself very slow and sometimes crashing because of load depending on spikes, unless they opt for a server with more resources, for more money.
Any answer to that along the lines of "do something more complex" or "optimize your site for load" to be able to deal with the rampant bad behavior of multi-billion dollar companies is unpalatable to most.
