I've had my house egged and repainted, and been physically assaulted at events over baseless personal grudges held by others. You could tell me they hate the guy just for existing, and it'd be 100% believable.

If I had to guess - I'd say it was down to refusing their name suggestion. Which is a really damn petty reason to hate someone, but one I can entirely believe. One of the personal grudges I was dragged into was exactly that petty.

The internet has been well overdue for a good chlorine dosing for a long time.
