> Right, but how do I know that nobody's watching?
A better way to think about it is: do you have good reason to think someone is actively watching you or will go through the effort to collate your social media posts against some archive (that will be incomplete unless you're an active target)? If you don't, delete away.
If you're still concerned, delete some old stuff randomly to distract from the stuff you really want to delete.
> even if that somebody is some Internet archival robot
Those can't even scrape everything people actually want to keep, let alone comprehensively scrape every social media post from everyone. There are huge gaps.
I actually was peripherally involved in some volunteer efforts to archive a bunch of stuff around the Hong Kong protests and the Afghanistan withdrawal. IIRC, they didn't even try to scrape Facebook posts (because FB was doing so much to thwart scraping, and there may have even been problems with Twitter). There are well-developed tools for YouTube, through.
