How Would You Handle It?

Well that whole situation just does not say so much about that Mothers character. Why would a mother tell her kids about what their friends mom has posted? Some mothers just baffle me .
I am sure you have already told her to confront the mother, and she said "no". My other suggestion would just be to get off of the site that , that woman is using. I would also let the kids know, that , mommy is sorry that happened.
If the mother is not willing to confront the problem at hand, then she does need to not use that site, otherwise it will happen.

Perhaps it would be best if the "post-er" did not provide enough information to be so easily identifed? Past that, you can't help it if other people act crazy, and some of them occasionally do. No point in wasting your time and energy worrying about someone else's bad behaviour. I'm so sorry that happened, this is supposed to be a "safe" site. I would report the person that violated the rules and request that they not be allowed to use the site any more. I'm not certain, but I think this is an "invitation only" site? Good luck.

That's an awful thing and how dare that mother go telling the children about something that was post on a website like this one that is meant for mature adults who are seeking help. However, that being said, whenever you post anything online, whether it's on a forum like this or on social networking websites like Facebook or MySpace, you are taking a risk that something you don't want everyone to know will be seen by someone you might not want to see or read it. Even "anonymous" postings can be tracked back to an individual computer's IP address by a tech savvy person. That's just part of the risk with using the internet. If she doesn't want to confront the issue, yet it bothers her nonetheless, then she isn't prepared to take this risk and should not have been posting online in the first place.

I would stay away from her (and the site) as much as possible and when I saw her I would treat her kindly with love and forgiveness. I personally would let it go. It is not worth holding onto bitterness and unforgiveness. It will only end up hurting your friend more and the other person will probably not be affected either way. As to the "lies" that were told: the character of your friend should make it obvious they are just that--lies.

You didn't mention where exactly on their body it was. If it is on their groin area, armpits it could be scabies. HIGHLY contagious.
