That’s why I suggested the entire netblock. Start by filtering localized ISPs networks, which may block some legitimate users but is it totally acceptable collateral damage, then if necessary, whole geographic netblocks, so you’d have to change states or, more than likely, vacate the entire geographic region. Then it can move on to banning all your known e-mail accounts. You’ll have to register so many random, anonymous e-mail accounts at various services to keep registering here, that you’ll be flagged as a spammer by them. Then comes the ISP banhammer… U MAD?
