well EQ2 has the bennifit of a prophanity filter, thus as long as you are not being beligerant you can curse pretty much as you wish. Dont be an ***, but the ocasionaly placed curse word in open zone wide type chat channels are usualy ok. Cursing in /tell or group chat or guild chat is not GM regulated, it is regulated by the people participating, again exercise tact ( if thats realy possible to do while swearing ) but no one is realy going to stop you, and you wont get banned for it.
