of the women (and I use that term loosely here) who would want to post to such a site.
Let's face it, neither gender has a monopoly on individuals who are sleazy jerks. Men can be a$$holes, so can women. Why are we always so surprised when women do foul, sleazoid things and not surprised when men do?
Secondly, I'm not sure if there are ramifications in saying someone's a slob...but there very well could be if you publicly accuse someone of having a sexuality transmitted disease, being a deadbeat parent (again, not necessarily gender-exclusive behavior), etc.
With employers googling and researching the Web for info on prospective or current employees and even firing employees over MySpace.com entries, such comments could have serious reprecussions for the accused (true or not, that's almost irrelevant).
The site owner should be held accountable for comments along those lines--when in doubt, take it out (before it gets publicly posted).
