Apologies. I suppose I should have known this, but I didn't (I've seen many such headline over the years).

> But the ruling doesn't threaten to ambiguously target people who just change an IP to get around an ordinary IP ban.

If this ruling sticks, I can imagine that instead of blacklisting an IP, standard practice will be to return a web page saying "you are hereby notified...".

How do you legally notify someone if all you know is their IP? (serious question, IANAL)
