text: Salut!
  I saw that there are many buildings here and in some other cities in RO that use "addr:housname=Bloc" and "name=Bloc". I believe these tags are not needed in any of these appartment blocks. It is redundant data: the tag building=apartments already shows that it is an appartment block, and the "addr:housenumber=Bl. x"  is also making that clear.
  "name=Bloc" is probably even wrong, I suspect that none of these buildings are really named like that.
