Harsh blocking/limiting/challenging is way too valuable to sites that are actually trying to make money online. It's not going away short of legislation banning it. Losing 1/10,000 legitimate customers to cut fraud attempts, spam, exploit attempts, and so on, by 90% or more, is just too good a trade-off.
I have bad news about the most-likely fix for it, longer term, so we can lay off the IP-based reputation stuff and the geo-blocking: it's tying some form of personal ID to your browsing activity, so that bears the reputation instead of the address.

Sorry. Said it was bad news.
