I would generally discourage trying to game the system with resubmissions. If you resubmit - at SS and DT there's a field where you can put a note for the reviewer; I wish all sites did this - make sure the file is different or there's some type of note explaining why you want the file looked at again.
Sites are not always consistent month to month (or weekday to weekend) - inspection systems may have guidelines, but there's a lot of judgment calls made by people as well. I've found 123rf and Stockfresh to be the most conservative about requiring property releases for things shot from a street or other public place. Not talking about famous buildings with famous architects, but things which a few years ago would have been accepted by all agencies without question.
As they make more money, the agencies get more risk averse. For the most part I don't mind as long as I can get a clear picture of each agency's foibles so I can work around them. I don't remember hearing about any legal action taken against any microstock agency or photographer over a property release issue, but I wouldn't want to be the first
