    Reddit has some pretty good spam prevention stuff. As well as detecting vote manipulation (presumably done by measuring how fast upvotes come in or the IP addresses they're coming from), this comment claims they intentionally hide a submission's actual number of upvotes so bots can't tell that they're banned. They do some good stuff, but when you're the #10 most visited site in the world you'd be expected to. :P
