The question has been resolved
How do I delete this?
not sure… I thought there was a delete option for your own posts or an option where it used to say that if no one flags it then the post would be deleted in 24hs or sth like that…
oh yeah clik on the … button next to the flag and then it comes up a bin! 
I tried clicking the buttons next to the flag and there is no delete option
You can only delete responses, not the original topic.
