I think Jagex have updated the game so there are a lot more Afk methods to train and so on, the nightmare zone for example is very afk. Why would people run the risk of getting banned when they can train with very little effort. Also no randoms in pvp worlds so people can splash train their mage and leave the account logged in for hours (which is completely legal according to jagex). Both of these pretty much discontinue mage and combat training scripts, and as everyone knows if you bot money making methods its 90% of the time a perm ban so for the most part with the ban rates now it isn't worth it, so really Jagex have won.
