All you know how facebook interns love to disapprove ads. Or maybe they have some sort of point system: you have to disapprove 1000 ads to earn 100 approve points
And after ad has been disapproved - 'Create similar ad' link are gone.
Here's small hack to make your live easier:
1. Delete disapproved ad. You will be redirected to URL something like this:
hxxp://www.facebook.com/ads/manage/?act=1234567&ag=1234567
2. Change URL to:
hxxp://www.facebook.com/ads/create/?act=1234567&adgroup_id=1234567
And now you have prefilled ad form.
Enjoy
P.S. Have you tried Safe Facebook Cloaking(by IP addresses) Script?
