Can we have one? It would stop from people giving repetitive/bad suggestions and give an idea for what you guys are aiming for.
Example:

http://yppedia.puzzlepirates.com/The_Anti-list
EDIT: heck, you can even just make a locked thread and put posts that you liked or didnt like
Repeated threads is one of the main ways that the devs and people in general can tell that an idea is popular. If people keep suggesting the idea without knowing that it's been suggested before, that must mean it is needed in the game.
And putting up a list of what NOT to suggest will limit the playerbase's creativity as well as insult players who come up with those ideas. There's no need for any of this.
