I find many questions on http://unix.stackexchange.com/ which, I feel, should be searched for on Google before asking here. I am sure that there are many others who feel the same. Does SE have some provision for preventing such stuffs?
What I feel is that people who ask such questions here are either too lazy to Google or they're too conscious of reputation score on SE. Recently I came across few such questions and that's what made me write this post.
Can such users be requested via email to try to do some homework before posting here? Or, in extreme case, can they be suspended/banned? In this case homework just involves querying the question on Google.
