There are a bunch of questions asking to evaluate the security of an amateur cipher, clearly without knowing pretty basic stuff on cryptography or how SE works. You all know the type of question I'm talking about. Since these questions are highly unlikely to be improved by the OP, for example, by restricting the scope or by demonstrating any type of preliminar analysis, I believe we should directly close them, as we already do with requests for deciphering blocks of data. Maybe this could be added to that close reason.
What do you think?
