I don't see anything here that you can't say to quite a lot of people. And I'm not surprised. After all, if you couldn't say it, you sure couldn't publish it for the world to see.

A genuine list of things you can't say has not been written and will probably not be written, because such a thing is nearly paradoxical. Even if someone is foolish or suicidal enough to write one, nobody who reads it will want to pass it along to anyone else as that would taint them as well, so it will remain obscure.
