Are you referring to the Fandom 'Wiki'?
They start to nuke 18+ stuff, due to it's bad for Advertisement money.
It's a disgrace for being a "Wiki site", especially when all contents they sell are user generated.
People should've stopped to use Fandom a long time ago, when they switched from "Pro-user" to profit driven, full of intrusive ads and terrible user interface.
They don't care anything else but money, it is bound to happen.
Tho this might be the tipping point, some wiki site with better integrity might over-run Fandom.
