Ok, so I had to see if I needed to keep it pruned or not. Then it became, "Can I break this?"
The natural place to start was to go into the threads in long-forgotten corners where people pump up their children as prospects and Ignore everyone in the thread just in case they ever wander out of their pens. As I said, my last guess was 2⁸, or 256, but we're still good to go. This train will never stop. One bad word about tamales and I'm hitting 258.
The fact that you are actively seeking out people to ignore amuses me to absolutely no end. I'm actually cackling right now.
