Reddit FRANK Detector
F.R.A.N.K. - Fresh Reddit Account, No Karma This extension checks Reddit comment authors for low/negative karma and new accounts. It then flags any offending comments. To put it simply, this extension makes Reddit trolls more obvious. This is not the world's most sophisticated troll detector but it will quickly identify the most obvious offenders. You will be surprised how many obvious trolls are hiding in virtually every thread.
