Hi, thank you for the quick reply. We have a complaint from Farys who suspect that we have copied data from their copyrighted maps. You have made a large number of edits to Farys pipelines in the past months, e.g. https://www.openstreetmap.org/way/1392283607, https://www.openstreetmap.org/way/1416793845. Are those all from survey and local knowledge as well? 

Could you send us a few photos of these markers that you speak of, so that we can tell Farys that these markers clearly indicate where the pipelines are and that the data does not come from their maps? 

Also, when you do pipeline mapping in the future, please be sure to always specify a source directly in the changeset to eliminate any doubts.
