Is mywot.com Safe?

Less than 24 hours after criticizing the reliability of ratings through WAT, the retaliation began. I'm only leaving a comment here so that there is no doubt mine are NOT retaliatory. I feel that this is highly a highly untrustworthy and easy-to-manipulate model; there are no real guidelines given for each of the four areas to be rated; and any sites run by and used by people who are so quick to pounce on any criticism with retaliation are NOT safe for children, in my opinion.
