If someone reports you, yeah. Usually people don't report like little kids, but yeah.
I got reported once for standing next to my friend in Tree form, and typing /e pees on you. As in peeing on a tree.
I got a mail with a warning. Granted not a suspension, but it may depend on your history or something. Do you have a history of warnings for language at all? If not, then I dunno, that seems harsh.
I got a warning another time for typing something disgusting in trade chat along with a bunch of other people talking about it. I accepted that, even though trade chat seems to be basically no rules. I limit my cursing to Trade and private channels. General chat seems off limits I think.
Anyway, the emote thing for peeing on a tree really annoyed me more than anything, because this is a game where they have quests to poop and emotes built in that fart and belch and so on and so forth, so peeing on a tree seemed stupid to report.
Whether you agree with it or not, "not swearing" is actually part of the ToS. It's just that it's obviously never reported because no one ever really cares. However, the swearing plus your general bad attitude are probably what caused the GM to decide to give you a suspension.
Not saying I agree with it one way or the other, but that's why it happened.
