Bongobing may not appeal to you, but it is a valid attempt by a student who is attempting to learn. By that standard, they deserve our honest opinion. They obviously need to be pointed in the right direction, and I don't feel that "No." necessarily accomplishes that. I'm surprised so many people have voted this comment up as it does not contribute to a thoughtful discussion.
Curt negative feedback isn't helpful. Comments -- especially to students and others asking for help in good faith -- should include some morsel of information that can be used to improve.
