discontent aggregator
A discontent aggregator is a website or other publication composed primarily of articles seeking to expose, shame, and/or shower with contempt any person, organization, or pop-culture belief or artifact that offends the aggregator's particular ideology. Discontent aggregators are like content aggregators in that they produce articles about nearly everything in publication, but differ in that their articles primarily focus on criticizing every topic for violating the aggregator's beliefs.
Both the Men's Rights website, ReturnofKings, and the Women's Rights website, Jezebel.com, would be examples of discontent aggregators.
