From the wiki: As either alignment there can be times when you are not sure what you want to post - or if you want to post at all. This is normal. However, posting is generally seen as pro-Town while not posting simply lets the other players continue their trains of thought without interference (which is usually only useful for scum). Note that if if the game is at a standstill, lurking is profoundly harmful to the Town. While some people are capable of lurking as a playstyle regardless of alignment, people don't like playing with lurkers in general and frequently criticize them for looking unreadable or scummy, making them choice policy lynches/vigs as well as objects of public ridicule. (Note that lurkers are not always unreadable or scummy, although the argument that they're not making the game any easier for Town is usually fair.) Note that you can go too far with this - there is such a thing as posting too much. If other players are having a hard time catching up on the discussion because of the immense volume of posts that flowed in while they were away, it will hurt those players' contributions as well as your ability to read those players. It is possible to use this as a tactic as scum, but it has a tendency to result in inactivity replacements/modkills as the other players prefer to just let the game go instead of reading it all and trying to make sense of it.
