89man was similarly minimally active in the last game and he was a C then too. And to be honest, I find there is a point in keeping low-profile players around (as long as they make the minimum), if they're C's that is. Having a high C-to-G ratio is important, the only time someone should be lynched if it's fairly certain they're a C is if they're doing something stupid to sabotage the game a la ILFJ.
Of course some might read this as an attempt by me to use 89man as a shield (and if you lynch him and he turns out to be a G I'm fucked), but really I just don't see the point of lynching someone when we don't even really have any hunches about him, it'd be like doing the G's job for them.
