If someone is saying something that you don't like, the best way to deal with it is to put them on ignore. You can do this by tapping on their profile page and then taping on the mute sign, which looks like a red speakerphone with an 'x' on it. Make sure that if you are friends, you unfriend them to prevent them from following you. 

You can now block other guests completely and ban them from your rooms. It's easy to see who you've banned and blocked. To see a list of blocked guests, tap the new block button in the 'Me' tab. To see a list of guests you've banned from one of your rooms, tap the block button located in that room's profile window.

We've also given you the option to kick guests from your room without blocking or banning them. This should be helpful for those of you who host games and other activities in your rooms!
