I'm not really sure what to make of the apparent success of Hareidi rabbis and Rashe Yeshiva in closing down a number of prominent websites that catered to their communities. On the one hand, I understand wanting to keep the salacious and undersireable elements of the internet out of the community. On the other hand, doing so is a truly Sisyphean task. Do these rabbis really think that by driving these portals out of business, they will keep people from the net? On the contrary, these 'safe' portals served a valuable function in providing information without blind links to undesireable sites.
I suspect that there is a deeper motive here. These websites provided Haredim with a place to vent; to express themselves on issues of moment, and often in contrast to the official organs of their community. In other words, this is a bald attempt to shut down dissent.
It won't work. It can't work. It might, however, return to haunt and undermine the authority of those who enacted it.
