How the problem and request are presented matter. "I don't know where to start" is a different problem than "I've done nothing, just solve this for me." And how someone shows an effort was made will vary person to person, so I agree a strict formalized set of rules doesn't make sense. The concept boils down to "expect people to put forth some effort of their own"
"Teams" are also going to have different dynamics than "strangers on a help forum."
