This is a big enough problem that there's not just one startup idea here, but several. For example, there will probably be one variant meant to filter out agents, but another meant to welcome them in an orderly way. This also seems an idea you could build more on.
@tnyxdr@paulg It’s actually possible to detect agent behavior compared to humans on the web. But the best way is to build a separate entry point for agents that’s faster, more efficient and cheaper.
