This person does not seem to know much about how GMs catch bots, those are pretty nooby ways of bot hunting in my opinion and I have never resorted to it. ( I am referring to the teleporting bot to another map ) There are so many better ways to catching a botter.
As for crashing players to run bot checks, its completely unnecessary and it is abusive to the legit players. Like I said, there is way better ways to hunt bots.
And lastly @hide, if you are experiencing no sprite when unhiding, the simple thing to do is type @goto player, this should get your sprite visible.
