Hello Ant Ko and welcome to OpenStreetMap!

You’re welcome to add real places to OpenStreetMap and to help map the world around you. However, please don’t add imaginery data - OSM is a real map of the real world. If you’d like to create an imaginery world map then I’d suggest instead http://opengeofiction.net/ - if you create an account there you can create imaginery maps to your heart’s content. Most of your imaginery additions to OSM have already been removed, and those that have not yet (e.g. https://www.openstreetmap.org/way/534200051 “Rainspell Island”) soon will be.

Once you’ve finished reading this message you’ll be able to edit OpenStreetMap again but please - only add things that really exist. You can see a list of places where people have commented on your changes at http://resultmaps.neis-one.org/osm-discussion-comments?uid=6750990 . They’re trying to help you - if someone asks you a question there please do reply to it.

Best Regards,

Andy Townsend, on behalf of OSM’s Data Working Group.
