# Use SwearJar to moderate and censor bad words. **** you!

An easy way to find and censor profanity (bad words) is to use the gem [swearjar](https://github.com/joshbuddy/swearjar){:target="blank"}

```shell
# terminal
bundle add swearjar
```

```ruby
# app/models/message.rb
  def moderated_body
    Swearjar.default.censor(body)
  end
```

```diff
# app/views/messages/_message.html.erb
-<%= message.body %>
+<%= message.moderated_body %>
```

Result:

That's it!
