I'm not sure PETA would do that, because they're a legitimate organization that could have action taken against them. But that's an interesting point: if every IP address was reported, how do they enforce or verify it?

Personally, they can pry my internet from my cold dead hands.

I really doubt this is going to be some grand populist legal tool.

And if someone mildly technically knowledgable gets involved you could really cause trouble. Imagine the havoc that could be wreaked by AT&T disconnecting Verizon. Or shutting down Dreamhost.

Instant disconnection on accusal is a recipe for stupid things.

Hell, someone would probably set up a linkbait news posting to a webpage that they claim is protected ip and have a script issue automatic disconnect requests to everyone who views the target page.

sounds like a good way to shut down supporters of XYZ cause

Or, in fact, come from the people it claims to come from.
