There is a difference between voting to get to a point of discussion and just voting names to vote random names. Just throwing out "vote x" without reason or backing or anything does what good for discussion? There is a clear difference between a response like "Vote X" and "Vote for X because X has been acting pretty minimalist and seems to be playing things pretty safe. I've played in a few games with him before, and expect more. What's so different about this game and why aren't you being more active?"
One generates discussion, and the other is just posting to have your face on the thread. I'm not saying it's scummy, I'm just asking what does it do?
To me, most everyone (I hope) can see red flags when someone posts a "hi" post or is being minimalist. There are two reasons for that. Maybe they're being minimalist because they're mafia and want to stay in the middle of activity and inactivity to avoid attention. In this case, calling out the behavior early without seeing if it goes anywhere diminishes the effect, because they're pressured to change their behavior when it's too early to get a reading on what they're doing.
I like to observe natural behavior. Maybe that's not everyone's thing, but before we pick apart people for doing things I'd actually like them to start doing things... ya know? To do things, you need to start conversation of merit and make people answer questions. Make people give effort and be logical. Because pressing someone into a conversation that might reveal something is WAY better than just voting them without follow up. And then we can move on by pressing people on their reactions and the ball rolls from there.
