I agree, we should have some system in place to avoid commissioned works being taken just like that. Maybe at least some lower quality?

I have to say that when I am in a hurry and scan what is new on here, I do not always read the complete info on it. In this case, the only reason I noticed this map (which is very cool) is a commissioned map was because the first post missed the map so I read it in detail. I can imagine quite a few who mainly read do just the same without any bad intention.
