I noticed a question posted to the front page with a title of "jfklsad jfklsdj flksdj flksd flskdjf sldkj fklsd jfklsd jfklsd jfksld jflskdfj sdiojfsladfk ;sd".
Thinking that this was finally my chance to earn my "Citizen Patrol" badge, I opened the question only to find that the question was normal.
I opened the user page for "ginius", the user who posted the question, and sorted by "Most Recent". As I refreshed the page, I saw titles with gibberish text appear, then disappear as a high-rep user would roll back the question to its original state. As an example, look at this revision history. To my knowledge, this is still occurring (8:37PM PST).
What's going on?
Edit: The account in question has been "temporarily suspended", so it looks like someone caught it. In the future, what actions should lower-rep users such as myself take when several of a user's posts are being modified? Should we just flag the affected posts, or is there a way to bring a particular user to the attention of a moderator?
