Maybe this actually exists and I haven't noticed
I could use a second AO3 savior that would take a blacklist and just hide the words on it while still letting you read the rest. There'd be a blank space or something, so you'd be able to guess which one it was from context, probably, but it would spare my eyes from pairing name portmanteaus and a few hideously unsexy terms that have a distressing tendency to pop up in sex scenes.
