Gaslighting is a behavior often encountered in FM. This thread is here for people to discuss both the moral and strategic aspects of the topic.

First, to keep things clear : personally attacking a player, telling them they are "simply too dumb to play this game", etc. is NOT allowed on this site (and on most other sites). That being said, gaslighting does not stop there.

It is quite common to see townies, and more rarely, scums, question their own choices because of their own doubt; it is also common to see people (often the target of the victim's suspicions) try to make others doubt of their own reasoning without directly entering an argument with them. My question is : do you think that gaslighting is a valid strategy, both efficiency-wise and moral-wise (excluding the rule-breaking version of it)?
