Dug this comment by a level designer up for you; https://www.reddit.com/r/Warframe/comments/93ehrq/why_i_hate_wallhopping/e3d3hzz
Basically:
send it to support.https://digitalextremes.zendesk.com
Send it as "Logs and Metadata", with the category "Level/map Screenshot metadata".And include the screenshot.
Make sure you upload the raw screenshot as an attachment, make sure you got it by pressing f6. (don't upload it imgur or something first) - they need the metadata intact.
Hopefully it'll be fixed once they get the time then...
