"Is this some sort of score system that damages your reputation?"

No, it just tends to piss us off when you give someone an accurate answer and the say it wasn't helpful because it wasn't the answer they wanted to hear.  We are all volunteers trying to help out other preparers so a little more appreciation of volunteers really couldn't kill a person.  Try helping here once in awhile instead of just asking here and see how you feel about it after a while.
