Found two instances of multiple entities that share the same address, with a separate marker for each entity:
1. A suburban city government, with all departments (e.g., purchasing, HR, finance -- departments that usually don't interact with the public) housed in the same building but each dept having their own individual markers.
2. Multiple business listings sharing the same address at a mailbox center. Clearly this is their virtual address is not where the businesses are actually located.
What should we do with these markers? My thinking is that they should be deleted because:
a) Reduces duplication.
b) In the case of virtual business addresses, the marker doesn't help anyone find where the businesses are located (and with these businesses, it may not matter where they are located).
c) Even if the markers remain on the map, since they would all be stacked on top of each other, if an entity I'm interested in is buried underneath other markers, I won't be able to find out more information about it because it's blocked by other markers on top.
