Like many others, I keep FB around to see updates from family/older friends, etc.

What I've noticed is that every couple months they decide to update their feed algorithms, and my feed reserts to the garbage feed.

For ads: I've found that clicking the post options and REPORTING the post is the only way to filter this garbage. (I usually choose spam or "false news", but that's just an indicator of how the algorithm views my engagement).

For promo posts: I snooze the user for 30 days, and often the campaign doesn't run long enough (or I filter enough to push me out of the demographic) so I don't see these again.

Overall, it takes about 15-30 minutes every couple weeks or so, and has been generally useful to find similar methodologies across platforms

An internal wiki like Docuwiki or wiki.js might suit your needs. Although they won't automatically categorize\classify anything, it could be a useful searchable repository (especially if you can train your team in standardizing descriptions\tags\categories\etc).

I started reading Mort (Terry Pratchett) and it reminded me of the Discworld MUD I played with my friends in the 90s, on dial-up, all crowded around a single 13" CRT. I looked it up, and it's still running!
