Compare his campaign messaging with some of the messaging out of the clinton machine and you will see how deep it goes.
Consider Trump's 1) Make America Great Again (subtext: we've been letting the establishment make america not-great) 2) Build a wall (subtext: I'm going to do something audacious and unpopular and there's not a damn thing they can do to stop me)
Clinton came back with several messages beyond the core "I'm with her" and none of them stuck, because they were the sort of thing you'd hear the teacher's pet say. Nobody likes a teacher's pet--they're no fun at parties.
Who determines what is "good-spirited"?
I've been a part of many prank wars. You know when they stopped being fun and ended up getting people in trouble? When one side stopped enjoying it. I don't think the receiving team in this case is enjoying the prank. Which just makes it mean-spirited and low class.
Anon is just being a bag of dicks in this case, which means they either stop, or should get in legal trouble.
Isn't there another term for a one-sided prank war? I think it's called harassment or something? Combined with theft and vandalism... I can see why they prefer to be anonymous.
It's hard to meme from jail.
