Hello and welcome to OpenStreetMap, Idarefama F Martins.

OpenStreetMap is a collaborative project, used by a multitude of people and purposes, including Pokemon (which may have been the case of some of your editions). We have to map only what exists in real life, without creating incorrect objects (for example, we should not map a lake where in fact we have a park).

If your goal is to draw nice fictional maps you can take a look at http://opengeofiction.net

After reading this message you will be able to continue your edits, but please, take into account what has been explained here.

If you have any doubts you can also contact us at data@osmfoundation.org

Thank you for your attention!

Best regards,
Nelson
On behalf of the Data Working Group
