Strangest user name, if you read me well you can see that I didn't eventually propose to BAN it. I said it was a boring, uninventive and silly way to solve puzzles. I would feel ashamed to use it.
So, limiting it to a 7, 5,12 or 15 letter range doesn't make it less stupid.
So, everyone is free to use it, or to be a truly elegant puzzler and make educated guesses. And the puzzle poster is free to answer the 452 posts it will eventually take to narrow it down to the solution, or, like Otto did, to declare that he has better things to do.
