In the Colonial Marines SS13 mod the swearing is allowed and I don't believe it got overused in the roleplay. Sure the amount of swear words increased as the situation got more heated and the bodybag count increased but I do believe it added a bit to the authenticity of the situation. I highly doubt any lowly persona when pushed (along with the excrement) towards the fan is going to keep the language etiquette proper. I personally would prefer the swear filter removed from both ingame and forums but I'll most likely live if it doesn't.
