qmarchi says it's not harassment and that it's trivial to ignore. Here's a chance for them to test their methods and to prove those methods work.
Or, if releasing their name and address for a 3 day experiment is too scary maybe they can accept that they've got it wrong, and that harassment is real and causes harm.
I agree that online harassment can be a serious problem. I mean, consider Ross Ulbricht ;)
But seriously, it's best to stay anonymous in contentious environments. You have a professional online presence, for sure. But you keep that clean. Everything else using your real name ought to remain private. That's how I play, anyway.
