I don't normally believe in doing this, I'm a live and let live kind of guy. But this kind of behaviour is not cool at all. Either my content (and others) is spammed with requests to 'poop at the mall' for him, or my inbox is spammed. Had to block him.
@StinkyBoy842 It happened to me once before, a stranger found my profile, shared my stuff and I was bombarded with abuse. I locked my profile, deleted some of my content, blocked everyone who shared my content or commented, then went back to normal. It wasn't pleasant but thankfully a one-off.
