Just saw one of the ads of a sub-domain, gettind displayed on another sub-domain of same site. How is this possible, since this ad was deleted around 5 days ago. Pretty weird.
Ads are stored in the site's cache. So they will be there for awhile. It takes around 20 days for an ad to be fully deployed (or removed) because of that.
but the thing to worry is, ads for xyz.mydomain.com appear on abc.mydomain.com ? both xyz and abc sub-domains are running coop. In other words, my site displays my own ads ?
