Why does modding exist?
How it has evolved
Modding guidelines - is it right or wrong?
Well, you might argue that the SoundCloud example might not apply that much to beatmapping, since there's really no approval standards on what gets published there, but still, as a place to share your creations, no one should order you to change anything. Getting your creations judged and approved is not the problem, it's the way they're being judged.
