ngl finding it really strange too. we're normalizing people exporting the burden of 'proof' that someone is worth their time. you're the one approaching their top level: if you want further details about the character or canon to help narrow down your starter, by all means, ask. if they take an innocent inquiry poorly or refuse to answer it, they're 100% the asshole. but it's not on them to try to lure you in by preparing character blurbs, or putting character bios in their journal, or — like i've seen a few times — sample threads so people can evaluate if you match up to their writing requirements.

you need to understand that most people hit up memes and bakerstreet because they want low-stress, low-stakes, quick and easy rp. if they wanted the formality of a peer review process before getting to tag, they'd be in a game.
