Seems like a good way for digg to shut these guys down is to pay for their services for a couple of stories. Then take a look at the first 200 or so users who digg the story - and ban them all.This isn't particularly efficient, because of the rate usocial charges ($314 - 400 votes). But having identified the users, digg could then look for patterns in the ip addresses, or ways the users navigate the site, and use those patterns to identify the rest of the usocial accounts. It surprises me a startup like usocial gets funding in this economy (if they did). Seems like it's an incredibly fragile business model - not only are they relying on a third party, but it's in that third party's best interest to make things as difficult for you as they can...
