I am not trying to cheat anyone. As you have mentioned yourself, buying and selling trust is trivial. I would like it to be done publicly, just like the buying and selling of accounts. Have you not suggested that it's better to have these things out in the open, so that naive users could learn that these things exist?
You can warn people without promoting it. Once you start promoting it (or standing by and watching while it happens) you are then liable for what happens after that.
