With respect to Susan, the previous reviewer, and without taking anything from the message she's sending about the use of such sites, formspring.me does have an abuse contact address and it's plainly displayed. It also has instructions for blocking people who have upset you in any way, and accepting anonymous messages is optional, not mandatory. I leave the debate over how much responsibility a parent should take, to others. I'm not a parent, I'm not qualified for that one.

As to the site itself, the idea is to allow people to ask and answer questions of each other. People may be anonymous, or not, or just ask or answer their friends. Abandoning all sense of security is optional, but if you do then you will get messages from anonymous and potentially unpleasant people. It's your call, as far as I can tell.

The site is becoming very popular, with something like 7 million hits a month or more, and although it would be cool to be an adult there and anonymously find your boss and ask him why he's such a prat, chances are that it's inhabited by teenagers who, as science tells us, haven't got fully-developed brains yet.

Virtual Reality, whether entered by avatar or text or video, is subject to different rules, different morality and different expectations than the Real World. Take a trip out of the Real World by all means, but don't expect Real World mores to apply once you're there. I guess if they did, then Virtual and Real worlds would become indistinguishable, and some of us would be very sad about that.
