That's a great question, and I hope you find some relevant solutions.

I would discourage you from using the "pied piper" metaphor to describe this. In the original legend from Germany, the pied piper uses his magic powers to steal the children of the town, and they never come back!

It's easy to imagine Internet censors loving this metaphor for uncensored Internet access: the thing that controls young people's minds and steals them away from the society.

So you may want to use a different legend as your metaphor for describing what you're looking for.
