The things that's truly amazing is just how inept the attempts at getting them blocked are.
In the UK, the big ISPs initially at least blocked only a single IP, so TPB have changed IPs a few times. Each time to a new IP in the /24 network block registered to them. Why the entire /24 didn't get blocked in the first case is beyond me.
Not that it'd have helped given the massive number of proxies, but it doesn't look like they were even trying.
It's not the ISPs behaviour I find strangest, though, but that the rights organizations have not asked for even marginally more effective measures, such as even asking to have all IPs owned by The Pirate Bay blocked.
I speculate that it may be an attempt to stem movement to the significant number of private trackers that dependably provide higher quality torrents earlier than public sites. Allowing TPB to stay up means that people must sort through muck and viruses to locate the content they want. For many, that is enough and they don't bother looking a little deeper.
