Dear m_bakhshipour, please refrain from altering any of the names of the Persian/Arabian gulf without prior discussion on OSM community media. If a discussion involving OSM community members from all regions bordering on this water body comes to the conclusion that a change is appropriate, the change can be made with a reference to a public record of the discussion in the changeset comment (not "no comment"). Any undiscussed changes will be reverted and, when repeated, will lead to account blocks. This issue is tracked in the DWG issue tracker under Ticket#2021050510000129.
