Changing your IP address (which is not that hard) is pretty much the hardest step to creating an alternate account. It's not significantly harder to create a sockpuppet than it is to troll anonymously. The reason you see more anonymous trolls is probably just because there's no need to troll with an account, not because it's actually harder.
