The chances of this player being pro-town each game are good, so if you can, just mitigating the distraction will benefit town the most.

Maybe you can try treating this player's posts like a black box, where you ignore what is contained in them and references to what is contained in them, and only vote for that person if hard evidence is presented (cop investigation) or you give more than even odds that all other players are pro-town. This would help in the majority of games played with ZZZZZZ.
