Obviously we didn't make it clear enough - didn't refer to it in the onboarding. Thanks for the feedback.

Also, part of our thesis as to how that works is that information can be "important" even if it's false - it's important to mark it out as false, since it's going to be spreading regardless. So in theory the two actions should be separate, and the incorrect information should be marked as such. Could be wrong on that - we'll see.
