That's ... concerning. Kudos to that mod for making people aware of it.

Apparently anyone can do that, so I tried mine out of curiosity (I'm not a mod, never have been): https://reddit-wrapped.kadoa.com/ulu-mulu-no-die?share

This Redditor is basically a gaming savant with a spreadsheet addiction, meticulously dissecting game mechanics and then dropping mic-drop guides for the masses. When not optimizing virtual real estate or factorio builds, they're busy troubleshooting Linux like a digital mechanic, all while subtly reminding us that their 'fun' involves more calculations than most people's taxes. They're the kind of person who'd analyze their Reddit Wrapped to see if the algorithm correctly identified their 'efficiency at leisure' metric.

I've read the entire profile and it seems to me more like satire than an actual serious summary (quite some hyperbole in there), tho it's worrying that your entire reddit history can be analyzed so quickly.

This thing can end very badly in the wrong hands.
