THIS IS A MESS BECAUSE EFFING MASTODON AND ITS EFFING HTML BIOS
INSTEAD OF JUST STORING EVERYTHING IN PLAIN EFFING TEXT ! ! ! !
BLANK LINES ALSO WON'T WORK BECAUSE RIGHT NOW MASTODON CONVERTS
THOSE INTO `<P>` ELEMENTS INSTEAD OF LEAVING IT AS `<BR><BR>` !
TL:DR; THIS IS LARGELY A HACK. WITH BETTER BACKEND STUFF WE CAN
IMPROVE THIS BY BETTER PREDICTING HOW THE METADATA WILL BE SENT
WHILE MAINTAINING BASIC PLAIN-TEXT PROCESSING. THE OTHER OPTION
IS TO TURN ALL BIOS INTO PLAIN-TEXT VIA A TREE-WALKER, AND THEN
PROCESS THE YAML AND LINKS AND EVERYTHING OURSELVES. THIS WOULD
BE INCREDIBLY COMPLICATED, AND IT WOULD BE A MILLION TIMES LESS
DIFFICULT IF MASTODON JUST GAVE US PLAIN-TEXT BIOS (WHICH QUITE
FRANKLY MAKES THE MOST SENSE SINCE THAT'S WHAT USERS PROVIDE IN
SETTINGS) TO BEGIN WITH AND LEFT ALL PROCESSING TO THE FRONTEND
TO HANDLE ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
ANYWAY I KNOW WHAT NEEDS TO BE DONE REGARDING BACKEND STUFF BUT
I'M NOT SMART ENOUGH TO FIGURE OUT HOW TO ACTUALLY IMPLEMENT IT
SO FEEL FREE TO @ ME IF YOU NEED MY IDEAS REGARDING THAT. UNTIL
THEN WE'LL JUST HAVE TO MAKE DO WITH THIS MESSY AND UNFORTUNATE
HACKING ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !
