Still going through his twitter..it looks like a bot account multiple reposts of same stupid memes, and the text he wrote makes him seem almost illiterate.
Also, I have not seen any chan isms so to speak, none of the verbage or usual memes.
Also found a series of posts alleging that Arnold Schwarzenegger was a Nazi and wanted to kick the Jews out of California, and that was bad. So, we can conclusively say he was not on /pol/ and they can't pin this on the chans.
