I have had plenty of my pm's go unanswered ... IDGAF ... didn't bother me, I didn't lose any sleep. I have also not responded to some absolutely ridiculous pm's ... didn't lose any sleep . Helps when you DGAF about stuff that doesn't really matter.
I like to pick up dudes from Home Depot and take them to remote locations and kill things... looks on their faces are priceless. Can't understand a word they scream...
