The best part is how little effort went into faking the praise. It's just so blatant, I am somehow left doubting its not fake praise, but fake-fake praise; purposely left there to undermine the link.
Actually this sort of obvious voting ring is the least of our worries; at this point it basically never has any effect other than grumpy comments by HN users who easily see through it, and often the culprits turn out to be people who are actually doing good work and are clueless about how to promote it, i.e. people much like the rest of us. Why they don't simply post it to HN with a description of why it's interesting is beyond me.
