When using the discord integration, using [prefix]rv will display the 10 most recent visited pages. if you send a crafted payload, you can do things like ping everyone.

To Reproduce
Steps to reproduce the behavior:

1. curl https://[DOMAIN]/```@everyone - ``` breaks out of the code block, @everyone is just a PoC ping
2. run [prefix]rv
3. See injectionon

Strip or Escaped characters so that this can't happen
