Originally reddit was a niche site with few visitors that was full of knowledge and a strong sense of community.
Then during Gamergate (2014), several organizational subs were created by rancid basement dwelling mysogitrolls that soon found that not only did they not get banned for doxxing and harassing people, that they gathered even more rancid basement dwelling mysogitrolls to their ranks and realized they weren’t as rare as they worried.
Then 2015 rolled around and a SHITTON of alt-right wastes of their own father’s protein came around for the whole trumpfest that reddit became at the time.
And they never left.
On the other hand, a ton of people who created content and supported other users with meaningful replies all decided it wasn’t worth the constant harassment, doxxing, malicious reporting, bigotry, botting and refusal of the admins to address said behaviors.
And we left.
So the only redditors still there are either shitstains or too emotionally invested to leave yet.
And that latter group will get smaller and smaller as the shitstains become louder and more emboldened.
