I think you are in the right here. If one is trolling an audience of one, it's not really the same dopamine hit as Tweeting a death threat to a Senator that thousands see. It gets boring quick. Also, troll management as a problem is sort of like the "What if I burn $100,000 on AWS in one month?" problem. It's a good problem to have, it means you have traction, and with patience and focus the trolls can be steamrolled.
