this, to a degree. only it started with project chanology, not gamergate. '05fag here. 4chan used to be pure chaotic neutral. there was no thought to morality one way or the other. the only motivation was the pursuit of lulz. one day might be closing pools due to aids, then flooding an epilepsy support forum with flashing gifs the next day, then catching and ruining a pedo or cat abuser the day after that. the morality of the raid was never a factor back then. the only thing that mattered was whether there were lulz to be gained or not.
raiding scientology was seen as the biggest potential untapped lulzcow back when it started. then it started getting mainstream attention. at first it was funny. "exploding yellow vans" and all that. but soon, people that thought we were raiding as some robin hood-esque "hacktivist" thing piled on and outnumbered the people just there for lulz, and it snowballed. Anon got twisted into some chaotic good crusader by newfags who missed the point, and then flooded out the oldfags.
then as a reaction, people pissed at the moralfags swung too hard the opposite way in retaliation. that's about when the /pol/ and alt-right scene really rooted, when before the serious moralfagging, everything was pretty tongue-in-cheek here on both sides. "the internet is serious business" USED to be a joke.
I haven't been on /b/ in years. I miss the old days. EFG. Oregon Trail threads. stuff like that. it was fun.
this has been your internet history lesson for the day, from your resident oldfag. now get off my lawn, you whippersnappers.
