The trick at avoiding any legal action as was described to me by a fellow who should know...
Establish an online persona via a public IP address, preferably somewhere that offers free wifi (airports and coffe shops are ideal), secondly use a secure VPN connection based in an Internet friendly jurisdiction (did someone mention Sweden?), ensure that if your publically accessible IP location is indeed public, be sure there is no actual physical or electronic trace of you at this location i.e. pay cash, cell phone off, hat, dark glasses etc etc...
Lastly, be unpredictable in your movements.
If they find you after those efforts, then they are likely to be the NSA or some other well resourced security service....in which case mayby you should have known better
