I don't think that punishing someone who has the initiative to post a bug report is the way to go. Making suggestions to improve the report is one thing; threatening someone that their report will be deleted unless they have even more initiative is another.

This always reminds me of elementary school "safties", who were given titles so they could stop kids from running in the hallways. Give some people titles and they become megalomaniacs, no matter how trivial the title.
