All of a sudden its okay to be awful in trade

I noticed that not too long ago people were afraid to use swear words in trade out of fear of being banned or suspended or whatever. People say whatever they want never suffer any consequence. I don't necessarily have a problem with it myself but if you're going to allow 13 year olds to play that game i'd assume you would at least make sure people aren't being ridiculous in trade chat. My question is, was there a policy change that allows people to act like that or have people come to the realization that nothing will happen to them even if they're reported? Thanks. I mean, i say offkey things in trade myself but i'm suprised by the contrast of trade chat of old, and the new revised super-tard eternal 'barrens chat' that goes on in trade as of late.
