you can go dark. Ditch your phone, use a car with no computers, an old car. Live in the sticks in a trailer. Do odd jobs for cash. Wear a disguise and on and on
...and wait for your brother to turn you in.
And if you were interesting enough that someone with clout wanted to follow your movements, they could.
By the way, I love the woods, hunt from a tent in the winter, eat lots of deer, but after several days of outdoor living, it's real nice to get a hot shower, and a bedroom that has controlled heat.
If some one is watching...why?
