Tought so, but now it says it's "too popular" and some features have been disabled, so it should be "solved" -- I definitely didn't see anything weird in the document.
Yeah, when I had replied it was unreadable as all of the text and been crossed out, random edits introduced, etc.
If it's not 'too popular', it defaults to 'suggestions' mode, which will show all the vandalism -- switch to 'viewing' mode, and you'll only see the original doc.
I didn't see anything odd either.
That's good, when I saw it the whole document had been defaced.
