Let's look at this sober and with out any hysteria:
E.S.A. HAS acted up on Abandonia... TWICE, and we're still here. We conformed and they where HAPPY with the actions we took.
I was one of the three that was here when the letter arrived (Kosta and Tom Henrik was the others).
The legal department was actually most helpful, extended the deadline and helped us digging out who owned what rights now.
They are humans also, and trust me on this, it's easier for them to just send a letter and ask us to conform, then going to court to have a specific provider block out a specific IP.
The servers are NOT located in thew USA. To see a good example of this,
http://thepiratebay.org/ - Started out as a swedish site. Pissed off most of the worldwide entertainment industry, was attempted to get knocked off the net, but it's still up and running.
Now THEY cost a lot of money in lost incomes, and will be subject to the ESA to shut out of the US of A.
Abandonia conforms to the Digital Millenium Act, and is thereby a bit more "off the radar".
