There are 2 kinds of filters on Amethyst

- web-of-trust filters: if 5 or more of your contacts have reported a post, that post will have a warning sign (that you can dismiss to see the post content)

- de-dup spam filter: if someone posts notes with the same content repeatedly, the app blocks the user automatically. To find their notes, you'll have to go to their profile & follow them.

Both these filters are on by default on Amethyst. If you go to Security Filters, you'll have the option to disable them
