I said this privately to someone claiming to be you but, here it is again:
I'm opposed to hate in all forms, including against people I dislike.
Moreover, even if your only goal is to reduce sync stalking, I think your proposed actions increase sync stalking, not decrease them. Think about it for a second. It's a zero sum game (game theory keyword). By escalating to attacks that anyone can do, you escalate the problem from a worldview where reasonable people can win, to a worldview where everyone, including sync stalkers, have an equal chance.
After all, "destroying others" through spamming bands and forums and taking down websites is something one try can do equally as well regardless of how objectively moral their ideology is. My goals and thoughts are on the very far future, long-term planning, and on that timeline, short-term hateful actions like this only help the sync stalkers by increasing the hate that is the norm in this environment, and drawing attention away from productive, cordial discussion which is what this forum is supposed to be for.
