Stack Exchange constantly encourages people to be more civil to the new users. People sign up to a new account on Stack Overflow, ask for someone to solve their homework questions, and get upset if an answer is terse or a moderator closes the question. So, a modest proposal:
Provide a setting to ignore new users
That's it. If you are person who cannot deal with fourteenth question about "How to convert these Roman numerals to Hex?", just block all questions by reputations under twenty. Suddenly, most of the questions of "There is an error somewhere. Here is all my code pasted without formatting" and "I tried this and it does not work". Poof! Gone. You get questions like "Why does my Python context manager swallow exceptions?" instead.
Before everyone piles on with the negative comments, the real question is:
Why is proposing this sacrilege?
