Some jealous idiot who is probably trying to sell their crappy van for more flagged him. These are the professional flippers I rant about often. Not only do they rip off old ladies and try and flip vans but they also flag all their competition on craigslist to try and skew the listings toward them. I get stuff flagged on craigslist all the time by competitors. It is easy to flag something. All it needs is like 3-4 votes and it gets "flagged". Your laptop and cell phone can count as individual flags, and then if you use a VPN you can flag stuff even more. That's how people do it. I had one guy who I knew exactly he was doing it, because he flagged my ad and then posted an almost identical thing 9 minutes later (and this was not a common item). So I flagged his post back and then texted him on his phone and said "Two can play at the flagging game" and that was the end of that he never re-posted his ad or flagged my item again.
