I don't like the Touch Bar, but I've grown to hate it less. However it does register unintentional presses regularly. And no, I'm not "using it wrong".
If these are truly unintentional touches, as in, you were not touching the bar at all and it registered a key press, then you probably have a hardware issue. I just replaced a machine that would self press the touch bar on the right side when putting any sort of pressure (like resting your palms) to the right of the track pad.
