Hello,
I'm adding this comment to each of https://www.openstreetmap.org/changeset/155077463 , https://www.openstreetmap.org/changeset/155077906 , https://www.openstreetmap.org/changeset/155077446 , https://www.openstreetmap.org/changeset/155077894 .  

Accusing each other of vandalism and reverting changes without discussion won't get us anywhere.  Please discuss these changes on the forum together.  Tags already exist there for https://community.openstreetmap.org/tag/armenia and https://community.openstreetmap.org/tag/azerbaijan .

Best Regards,

Andy Townsend, on behalf of OSM's Data Working Group
