There's now a (court approved) process that doesn't involve going to court for each domain, it's simply added to the block list.

There is no way that will be abused

Is the list publicly available ?

No I don't believe so, the original "source sites" are all done by court order, so people like ORG have reported on them, but clone sites, and new DNS names for existing sites, are simply blocked by request of the BPI.

"Once a site is blocked, its alleged clone sites can also be blocked, but in this case, BPI will be able to practice this without a court order. The decisions would be made between BPI and ISPs and will not be published."

This is crazy. I understand that the hammer needs to go fast in that whackamole game but they should at least publish the list of blocked domains to allow external verification. This is a slippery slope to censorship.

I'd say less on a slippery slope, more we've already fallen down into that hole...

There's already been at least once instance of the bpi blocking a legitimate site

you sound like you believe censorship was not the whole idea behind it
