From 2015 to 2019 Reddit ran a series of April Fools' Day social experiments — most famously r/thebutton, a 60-second countdown timer that a million accounts could each press exactly once — which fractured users into color-coded factions that observers compared to religions and cults.

Bill Cosby's June 2014 Reddit AMA and a later #CosbyMeme promotion were overrun as users surfaced the decades-old sexual-assault allegations against him — an early, vivid case of a celebrity PR push on Reddit and social media colliding with the audience's own agenda.
Across multiple AMAs beginning in 2013, Microsoft co-founder Bill Gates engaged at length on philanthropy, technology, and public health — sessions widely cited as a model of how the format can succeed, in contrast to the genre's many disasters.
During the GamerGate harassment campaign, Reddit communities — most prominently r/KotakuInAction — served as a major hub for coordination and amplification, as targets including Zoe Quinn, Brianna Wu, and Anita Sarkeesian faced doxxing, threats, and forced evacuations from their homes.
