Wolf,
Frumster is on the internet, and the internet is only allowed for parnassah reasons. So firstly, the young maidel or bochur need a heter from a rav to have the internet at home. Secondly, since the internet is only allowed for parnassah and bochurchik should only be spending his first 10 years of marriage learning, there is no way he should be allwed to use the internet. Therefore the bochur has to have a higher level of special permission for the internet, and once he is allowed on the internet, only approved places are allowed. Concluding that for the young maidel to find the right bochur, the site needs a haskama so bochurchik can go to it and for maidel’e to find the right type of bochur.
