Hello.  
  
The reason for closing the note has already been written. I wrote: "This note does not contain a useful information for OpenStreetMap."  
This means that I believe that this note does not contain a useful information for OpenStreetMap.  
  
A little more detail. Every day, users add the notes that don't help to improve the map. You may see examples here - https://www.openstreetmap.org/user/mavl/notes  
  
Sometimes I find so notes. Sometimes other users report about so notes (probably, users are afraid or don't want to close them themselves). If I believe that a note does not really report any information, then I close so note. I see this note is open now. If other users think that the letters "svSVV" help to improve the map, then there is no problem.
