It's not hard if you take a few precautions and don't need to hide from people with determination and resources (that translates into a spider on social media that performs facial recognition on every photo it finds, so not even a country). Get a new nickname (and stop using all associated accounts, including email), move to a different city, drop your old phone number and get a new job. Don't contact anyone from your old life. You've disappeared. Only real nutcases will try to follow you and unless they're also technically inclined or rich they won't find you. If you're trying to evade someone that's technically savvy you'll need to take steps to make sure you don't pop up on photos and perhaps adopt a different writing style. For more advanced scenarios it just keeps escalating to more and more difficult measures to take. For most people the really extreme measures aren't necessary.
