I spotted it a couple of weeks ago. I too wondered if I had been put on the naughty step but was assured it was now normal. Perhaps it is an extra check to prevent known scammers or abusers of the rules posting undesirable listings. The mods were pretty quick in clearing mine both times.
Hey guys: moderators have lives outside the forum and aren't doing shifts. They volunteer their time, so some patience is necessary.
even on eBay sometimes you will have to wait some time until the listing is visible and I am pretty sure a computer release the ad..
I had this happended to me on my last listing. I used common sense, didn’t ask anything, went to bed and next day it was visible.
