I think they should make the distinction between requests per second and bandwidth. Bots already surpass humans in requests per second, that's why I just block them. Most of them behave poorly and are coded poorly. Despite all their requests they do not use much bandwidth, with exception of targeted attempts to use bots to mirror libraries and the few that mirror or crawl all the objects within repositories but they are the exception in my experience.

Humans will always use more bandwidth than bots on average just from streaming movies alone. As a side note I just found that some of the bots can not negotiate with Post-Quantum Cryptography in some limited testing.
