This person made a sign to discourage an unknown neighbor to stop stealing their New York Times issues every morning. We get it, you pay to subscribe to the NYT, and the last thing you want is for someone else to snatch your paper before you even get a chance to read it.
But what’s really cringe here is the idea that we’re supposed to believe they’re somehow tied to Anonymous. What hacking powers are you going to use to take the thief down when you can’t even find out who the thief is! The NYT thief is more anonymous than the OP.
