Can the HOA use a vacant house to see into my back yard?

I am pretty sure you cannot legally stop them from accessing someone else's property to view into your yard.  Bigger question to me is why are they raising the issue and what authority do they have to tell you what color your pool is?  Is there something in the HOA documents?  If code enforcement has not issued citation, then the HOA could only take action if there is a violation of the association documents.  What can you do to stop them?  Theoretically, you don't have to do anything if you have not violated any restriction.  If they have nothing to enforce, they should not be wasting everyone's time.  But it is probably not worth your effort to try to get the board replaced at the next election, which is the only other way that the HOA might stop.
