I read your link. It's really great and should be able to take care of most things. Possible inappropriate posts can also be pre-identified and stored temporarily or in server cases (like multiple cursing or lengthy descriptions of violence etc.) we can not store the post at all and even give a warning/smaller punishment using algorithms.

Researching your post led me to a bunch of things like Probability interpretations, Dutch book and Quantum Bayesianism. So thanks for that. You might find the following interesting:
