Comment(by mikeperry):

 To be honest, I was primarily thinking about very large services. Search
 engines, large social media sites, and other services that measure abuse
 primarily in terms of the computational+monetary cost to them. My primary
 goal is to be able to provide a search engine with a "clean" feed of users
 that statistically can be regarded as mostly not bots (see #3962).

 However, that doesn't mean it doesn't work for other sites too. Your small
 site admin could flip a switch that requires new accounts to have
 completed increasingly larger amounts of work, until the trolls give up
 and go away. The Nymble literature caters to this use case, but the only
 limiting resource the literature seriously suggests is IP address (which
 seem to be not scarce at all if you are clever).
