Reddit FRANK Detector is a free Chrome extension developed by impossible. This add-on falls under the Browsers category, specifically in the Add-ons & Tools subcategory. The purpose of this extension is to detect Reddit trolls, specifically those with Fresh Reddit Accounts and No Karma (FRANKs).

The Reddit FRANK Detector extension works by scanning the comment authors on Reddit for low or negative karma and new accounts. It then flags any offending comments made by these accounts. While it may not be the most sophisticated troll detector out there, it effectively highlights the most obvious offenders.

With Reddit FRANK Detector, you'll be surprised to see just how many obvious trolls are lurking in virtually every thread. This extension aims to make Reddit a more troll-free environment by making these trolls more visible to the community.
