This topic will give you a good indication of what I think about someone who altered my map in a very negative way:

Basically screwing with the contents of a pk3 file is offlimits. If you modify a pk3 file, then it becomes an entirely new map that has to be downloaded to the client and they end up with mulitple copies of the same map all overriding each other.
Regarding Posters:
I did come to learn later that I had a few SS posters in my map and server admins replaced them with a modfile. That’s fine with me. There use was unintentional and it fixed the problem without releasing a new version. Posters are in the maps to add to the WW2 atmosphere. The atmosphere that I am not trying to create is one that bombards the players with clan advertisements or Porn for the kids. I don’t want to see this crap in my maps. Personally, I would prefer that nobody plays my map than play it with this type of graffiti in it.
Regarding Sounds:
Basically, the same answer. However, I can fully agree with you regarding sound files that x-rated, extremely loud, or just so annoying you can’t f**king stand it anymore. In all of these cases, you are dealing with either an inexperienced mapper, or an immature one. So if the map is still so much fun that you want to play it, make a .wav file that only has silence, name it the same as the offending sound and put it in a separate mod pk3 file.
In general, if you have a valid problem with a map. Try to contact the mapper first. They may be willing to help you with a fix. Just recently, I made a patch file for Praetoria so that the bunker clan could increase the frame rate for slower machines by making the fog more dense, and giving them some new sky textures. The original .map file is still intact. You only get the fix if you play on their servers.
And I agree with SAGE. I spent 3 years on Praetoria. I don’t want someone trashing it in 3 minutes.
