Does not anyone read Wikipedia guidelines and rules?  http://en.wikipedia.org/wiki/Wikipedia:Biographies_of_living_persons

Wkipedia's own guidelines sumns up the problem here very well:

People who are relatively unknown (Non public figure = NPF)
Policy shortcut:
WP:NPF 
Wikipedia also contains biographies of people who, while notable enough for an entry, are not generally well known. In such cases, exercise restraint and include only material relevant to their notability, while omitting information that is irrelevant to the subject's notability. Material from third-party primary sources should not be used unless it has first been published by a reliable secondary source. Material published by the subject must be used with caution. (See Using the subject as a source.)

Material that may adversely affect a person's reputation should be treated with special care. In the laws of many countries, simply repeating the defamatory claims of another is illegal, and there are special protections for people who are not public figures. Any such potentially damaging information about a private person, if corroborated by multiple, highly reliable sources, may be cited if the Wikipedia article states that the sources make certain "allegations", without the Wikipedia article taking a position on their truth.
