In the case of something like a social media account IF way back works that way to automatically index it wouldn't occur until a particular account becomes prominent enough to warrant that kind of archiving.

People are being cancelled over things being said while not being of any wide reputation.

Think of these whistleblowers, George Zimmerman, Nick Sandman, Melissa Carone and others who are regular folk suddenly on the spotlight being ravaged by big media and psycho woke doxxers etc. Way back has no reason to have a history on them prior to a spotlight event.
