city raze mechanics

[sqwishy]

Hi. AI have a habit of building cities in weird spots along borders. They inevitably culture flip but i find they have no buildings and are worthless. I'd prefer to raze them but the pillage option is missing. Is there some other way to raze or remove this city after if flips to me?

Cities can be pillaged as long as they revolt.
AFAIK the only other option is World Builder.

They declared war and I finally got to pillage the cities but now they're at zero pop ._.
