Hello, friend!
i think tumblr urls in the old superwholock fandom style are like those old household appliances that got discontinued because they had asbestos or uranium or whatever in them - maybe you have a beloved cousin or old high school friend who still has a dean-and-loki-in-the-tardis and sure it’s not great but what are you gonna do, make them get rid of it? come on, that’s katie’s url, she’s had it forever, it’s fine. but if you find someone that has a brand new castieldrinkingteawithsherlock then something dark is afoot. they have regulations against making any more of those. you should be able to cut tumblr users open and count their rings like trees. i bet some of you got horny reading that last sentence
