The researchers also asked the participants to rate how often they noticed ten different problems in the online forums. Visitors to NoFap forums reported seeing content that was often trolling (88%), misogynistic (73.7%), bullying (49.1%), anti-LGBT (42.9%), or anti-Semitic (32.0%). Additionally, a significant number of participants reported being told to harm or kill themselves (23.5%), witnessing threats to hurt others (21.1%), and witnessing doxing of others (17.1%) on the forums.
It originally started as a multi-thread rift on mysogynistic hornyposting, tired memes about communist secret police, and the late/post gwot trend of adopting some Arabic phrases as a way to ironically demonstrate rejection of the islamaphobic majority. The big haram greentext was an important part of it back on reddit, and the actual volcel police jokes were reasonably explicit with things like "please keep your bodily fluids to yourself".
It's meaning and purpose has changed here to largely being a mechanism for shutting down casual hornyposting to protect the site's culture of being welcoming to people who either aren't interested in or do not want to be around discussions of sex, but at least in my experience it remains playful and silly, with lots of variation and innovation and a long standing gag of trying to thwart or escape the volcel cops.
Related, it's wild that the original volcel oath gag is like, what, seven years old now?
