There's a bad apple in every bunch. You know, that girl that just won't leave you alone! Dangit!
Well, you can at least squelch the volume. Just right-click and the baddie, and select "Ignore" and you'll no longer hear anything that user says. Additionally, they won't be able to leave you comments, visit your scene, send you gifts, or even send you a valentine on February 14, so make sure you really don't want to hear another word!
Sometimes though, Ignoring is not enough. In those rare cases where things are out of hand, please be on the lookout for someone with "Vivaty" in their name to help you. In an emergency, you can also email us (please include a screenshot, or a transcript if possible).
