// @namespace      http://www.lysator.liu.se/~jhs/userscript
// @description    Removes all presence of Dr. Phil from Match.com. This might prove less than true, but so far, the tainted sections of the pages are clearly marked as such with id attributes containing the substring "Phil", and this script hides those sections. (And just in case it gets things wrong, it adds a little skull and crossbones icon there instead, and a menu command, either of which brings the doctor back again when clicked.)
