Ken, you won't get an email. You'll notice the ad was flagged when you go to your user account- manage ads.
I think it's Trolls...my prevent pyramiding ad was removed too but I didn't notice it until I noticed the TFO ad was flagged. So, I'll just wait awhile and avoid refreshing the ad when I do put it back up. When someone specifically searches for "tortoise", the ad will still come up for them.
I run an ad for my CTTC chapter, too. It has a link to our website and has yet to be flagged. That ad has run for over a year because I re post it when it expires.
