>...one exception: when the question has been asked countless times already, and the asker could have seen it if they had made the minimum effort of reading the community's FAQ. In which case, RTFM -- or rather, a link to the FAQ -- is the best response.

This is actually the RTFM-ish situations I hate the most; specifically as someone searching a forum and finding a thread or threads close to my own question, only to find the only responses are rudely unhelpful.

I get not answering an insipid post, or a mod locking/deleting one but replying to a question you find dumb or repetitive is a waste of time to everyone involved.

Just like "Don't feed the Trolls," I feel one shouldn't raise the post count of a time sink.
