Twibooru is ran by a derpimod, Appledash/Floorbored, so it's fucked.
Don't worry, Rainbooru also has its trucks of shit. Doxing attempts, intimidation, flooding with gore/illegal shit or BLM bullshit, death threats and so on.
So it doesn't really matter which site is the greatest. They are all great.
I probably wouldn't call them marxists though. Or fascists, or corporates, or thots, or sjws, or wingnuts. They're all just… entitled jerks, who don't respect others.
It's fascism that censors art and burns books.
