I frequent the tags "order:note status:any" nightly. It's extremely rare but sometimes I'll find posts with outlandish notes (Note history on post #3237360) altered from preexisting notes. There didn't appear to be a thread for this phenomena so, uh.
In addition, I've been seeing posts not quite vandalized but, changed from English translations to Spanish. This doesn't strike me as vandalism but I tend to revert the notes back into English. Is that alright? I feel like there should be some way to simply add some kind of alternative notes to toggle if some users want a language other than English. Yet at the same time it might be sufficient to just refer to note history for either native speaker...
