Bandwidth is only expensive in the US, somehow. Here in Germany I didn't bother about bots and their additional traffic since 1998 (there are other annoying things about bots though).
More than that, it's practically impossible to find good specialized, human-written websites. Search engines don't find them, all results are AI garbage. With no real ability to be discovered, there's no incentive to maintain such websites too, and so the cycle of slop continues.
