You may have noticed when you tap the three little dots next to a post, you can downzap. This is kinda like down voting but you put your money where your mouth is. If a post gets downzapped by accounts with enough global trust, it gets outlawed. Outlawed posts don't show up in your feed unless you have Wild West mode turned on in your settings.

I like outlaws. If you like outlaws, or you just want to see where they are all hiding out, go to the link above.
