Agility "Glitch"

How are players meant to know this isn't how you're meant to train a skill? Shortcuts have always given agility experience- much like pickpocketing has always given thieving experience but Pyramid Plunder and Blackjacking always offered better rates. Am I to assume I can't pickpocket knife fighters because the experience is too generous? If anything, they're more extreme as the rates are better than the "real" method. Am I going to get banned for training thieving in this way? I can only assume so now.

Problems like the repeated teleporting are obvious- giving phenomenal experience rates in a method inconsistent with other teleports but this isn't like that. It offers a "good" rate but not the best rate and it seems logical an easier method is there to provide lesser experience. I'm sure I'm not the only one who got my first few agility levels doing the same obstacles repeatedly.

A few things. First of all, this glitch IS the fastest experience possible in the game (well it was). Timing it correctly you could get 80K max, the previous max was 72K from the Barbarian Extended Course. Also you could just position your mouse in one area, and even without concentrating hard 60K+ is easy (this is without a level requirement which is insane). Sure agility shortcuts give experience, but clearly not this much, and I think it was pretty obviously a glitch. Your comparing it to Monkey Knife Fighters does not make sense, blackjacking is a method of thieving that has already been used for ages. I am not saying Jagex handled it perfectly, it should have been fixed sooner, but I do not think they are in the wrong with this.
