I'm pretty sure that this particular one is harmless, but an edit to the answer How do I get a list of all available fonts for luaotfload? got marked as by "Community User". I'm guessing it was a suggested edit that got approved (perhaps improved?). But there's no record that I can see of who suggested it nor who approved it, which isn't perfect.
Can moderators see what happened (actually, should I as a 10k user be able to do that from the 10k tools?)? Whilst ideally it would be obvious to all and sundry who edited what, I'd be okay with knowing that the TeX-SX mods could see who did what.
