So far I've had one post stay alive long enough to make it off the front page of results. Within 24 hours of being online, that post got me 4 calls/emails and 1 application, so it drives me to keep trying, but I can't seem to replicate that posting's success. I emailed Craiglist and they haven't responded.
Yet at the same time, somehow miscategorized spam posts like "Yòu can Öwn a home" go unflagged. Not to sound paranoid, but it would seem that someone is out to get me and the unfortunate thing is that if anyone flags anything, it just gets taken right down so there's not much I can do except hoping that next time I put a post online, my nemesis is on lunch.
edit: Tried with 5 more listings. All flagged and deleted. Updated image.
edit2: I'm up to 20 posts in the past 60 days that don't last an hour.
