We NEVER rename maps, and i think we have no interest to do so (*).
We crawl games servers in search of maps that we don't have. When we find one, we upload it on our website with all the associated files that we can find (readme files, waypoints ..).
It is true that we do not always check the names of the maps. If the team or the server admin has renamed a map, we can not guess.
In addition, we have so many maps on our website that we can not remember a map is identical to one another. When we find one, 17b team or friendly members indicate in a comment.
You can not accuse us of hacking maps.
We are the only website that automatically extracts and displays readme files of archives or packed infos of bsp file to give full author credits. And each time we can add additional information of author (website, video, etc..) we do it.
So please, we are certainly not perfects, but we are not maps hackers and surely not mappers ennemies...
*: It's not really true: Because 17buddies doesn't accept maps with same name, I have renamed some maps one or two time when two really good maps were uploaded on our website and when i wanted to keep both versions because both were really good maps and each had it's place on 17buddies. I renamed the maps with _v1 and _v2 tag and indicated in comments the real name of the map. Perhaps should I not do that but I don't think it's an insult for the mapper and it's map.
