I am glad that Anet is keeping the GW environment idiot free. It's a great game, and I want the community to be as good as the game is.
Having said that- some people are reporting being banned by going AFK in big Dynamic Event areas and just collecting XP for doing nothing. Intentional or not, I like seeing Anet take a quick stance. Hopefully it all gets resolved without issue on the user end if it's a legit mistake.
