Thanks for your question, interesting discussion.
This phrasing is about signalling the kind of environment and culture we want to promote with the jam. Submissions do not really ever get taken down and we reach out and talk to creators if we feel the themes of their game are likely to cross a line that would be drawn with moderating in any community. We love gory and shocking horror games, and we want to make sure as many people can join in as possible.
