Oh I'm sorry let me be more clear when I say, make them fear you. Organize a group and surround their house, let them know you know where they live, let them know there are far worse things that could happen by accident than not being reelected.
That's whats needed for change. Non-votes don't mean jack shit, terrorism works though. Non-votes are just another vote for the Status Quo, and a "feel good" way to achieve nothing. Might as well go do a No King's parade for the same level of effectiveness.
