That's one of my all time favorite episodes because no matter how ridiculous "MeowMeowBeanz" is portrayed to be, it's totally possible. People will try to validate creating these apps, but at the end of the day they're profiting from bullying ("cyber" bullying is redundant these days) and young people's inability to ignore what's being said about them. It's pathetic.
Well I think the resolution is the same too. The only way to deal with this specific issue is to not participate. Implicitly all those people who are being effected by this are enabling it by participating in the activity.
I actually think this is easier to deal with then its non digital counterpart. Sure its easier to spread the gossip in a digital forum, but it should be known to be false. When gossip spreads through physical networks ( and is therefore not anonymous ) there is a much higher perception of reliability, and its much harder to shake then a completely unreliable and anonymous post on a gossip site which is not ever for a second pretending to be accurate
