Filtering "Good Girls" and IM Threats

Respecting your kids' right to privacy while wanting to ensure you're aware of the type of people they IM with? Consider a recently launched initiative, IMSafer aims to filter, not spy on kids :

"Keeping children safe from predatory adults in online communication is a service in high demand, but in order for children to participate the parental control needs to be kept to a minimum. IMSafer is a service that launched today and promises to filter IM communication for conversation deemed potentially predatory. The company says it worked with law enforcement specialists to develop its filtering rules and some of them are quite interesting - the phrase “you’re a good girl” is believed to be common language for building a dominance/submission based relationship, for example. Only questionable excerpts from IM conversations will be shown to parents; the company hopes that this relative privacy will help buy-in from kids."

Yet, this is a great example of marginal thinking when it comes to detecting potential child abuse activities with respect to little princess's -- why not prince? -- right to digital privacy. Whereas in the spirit of Web 2.0, the concept is primarily driven by the collective wisdom of parents participating and shaping the service's database and increasing interactions, IMSafer has already predefined categories of alerts :

"1. Someone looking to make direct contact (i.e. coming to your house)
2. Someone looking to make indirect contact (i.e. calling a phone)
3. Personal information (i.e. phone numbers)
4. Obscene language
5. Specific and sexual references to body parts
6. Specific references to sexual acts
7. Anything related to pedophilia"

Issues to keep in mind :
- the differently perceived dangerous or offensive conversation by parents
- the presumption that the "predator" would be using the same username next time, thus establishing long-lasting reputation
- how kids feeling in the middle of a silent war with their parents could simply IM from another location, one without the software installed excluding the possibilities of bypassing it with nerdy talk or vulnerabilities and hacks appearing on-the-fly
- monitors IM only, thus email, IRC, and forums remain an option for further communication

Don't emphasize on spying, not even filtering, but on educating your kids, thus gaining their participation in the process of building awareness on what's are potentially dangerous IM activities. From another perspective, do bored or adventurous kids spend time chatting with strangers? I think boringness, loneliness, the lack of strong, even developed communications with their folks is the root of the problem. And yes, predators acting as online stalkers, thus improving their chances of utilizing a long-lasting conversation.
