I actually made a mistake with it, sort of. I guess the bot looks also for poofofbrain, which mine reads. I'm missing the first r in proof.

I think that was the same tag that was posted on threads about the 999th user activating it. I forgot the account was actually proofofbrian, which I guess is a more common mistake to make. I wonder if Hive account@steevc has data on which mistakes are most common and what other tags it looks for.
