Indeed. There is something very familiar about the tone and content of these posts from haskeldownvot5. There was another individual that achieved a degree of infamy within the Haskell community for posting similar screeds to various forums. The claims that the Haskell community can't accept criticism, the accusations of the same 'lying' about performance, the referring to 'lazy evaluation' as though it were a carcinogen, the aspersions cast against the education of various individuals, both specific and non-specific...yes, all very familiar.
I think there's some interesting psychology at work here. haskeldownvot5 is clearly inviting downvotes by his/her choice of username as well as the contents of his/her posts, but I think haskeldownvot5 has managed to convince himself/herself that there is some cabal within the Haskell community that is responsible for the downvotes. There must be a name for the phenomenon where an individual brings things upon themselves and then uses the criticism/persecution they receive as evidence to the fact that they were right all along.
