Not content with accusing bloggers of sponsoring the hack of her website Claire Perry has further demonstrated her lack of understanding of how the Internet and indeed her own filters are going to work.

@claire4devizes No it's not, the ISPs will probably apply a filter within their core routing / aggregation the same way they handle IWF.

Whether she is confused, isn’t concerned about the details or just hasn’t understood what it is she has done the fact remains that ISPs are interfering with your traffic after it has left your modem and entered into their transit network.

They are mis-routing packets, spoofing DNS and who knows what else all in the name of filtering.
