That would definitively be the traditional form of dealing with this "problem," but if you are not going through a proxy, I might suggest that you start doing so. Also, be sure to change the MAC address on your computer (some free software is available that will do that), and try to use random IP addresses (laundry mats, libraries, rest stops, etc.) Also, get TrueCrypt and encrypt your entire hard drive using AES-Twofish-Serpent and be sure to use a strong passphrase, and be sure to keep your hardware physically secure at all times.
