Isn't it the same thing then? Just send a counter-notice to SE's hosts?
Of course, that doesn't stop all of Stack Exchage from being down for "10 business days" in the meantime. Should be interesting to see the public response to that if it actually happens.
Someone should issue a counter notice. And get them put back up.
What's interesting to me is what happens if StackExchange put these back up, and then the cryptocompany sends a DMCA to SE's hosts.
