FAQ Off allows users to create a gamebook-styled Q&A, which can be linked to when someone responds to a social media post with the same dumb question or tired arguments.
At the bottom of the page, you can link to more Q&A posts that contain further responses to the same, tired arguments.
In essence, it allows you to tell trolls, "FAQ off, dude!"
(For maximum impact, users are heavily encouraged to thoroughly cite their FAQ Off entries with a diverse range of reliable third party sources.)
FAQ Off is open source software.
