I picked several suspicious words and ran them through searchyc. The four rarest words in the post are: pure-ad, CTRs, disinformation, and dissimilar.

Walked through the results for each word, pulling in all the usernames:

    intersection of:  pure-ad dissimilar
    ['noodle']
    intersection of:  CTRs disinformation
    ['jacquesm']
    intersection of:  CTRs dissimilar
    ['ivankirigin', 'patio11', 'strlen']

Of those, strlen's writing style seems to be the closest match. So I'm changing my guess from randomwalker to strlen :)
