Limitless is correct. A few months ago, it was usually just kids or idiots that wanted to cause trouble.. So, I would either just ignore them, warn them or try to fight them.. While fighting seemed to work very little, ignoring them and warning them seemed to be the only thing to fight it. If you fight it, all you will get is carpel tunnel syndrome...I killed them with kindness, and that actually worked a lot.. Like asking them very nicely to stop..I know it sounds weird, but it worked...
