One of my friends was once nearly perm-banned unfairly for "impersonating jagex staff" from unknown causes. He had to spend half a week sending appeals to jagex to get them to let up.
It is all better than mystic but the hat, top and bottom are worse than Ahrim's robe parts which means that the gloves, boots, and book are definitely worthwhile ventures. (I want the book myself, would be handy for slayer) Plus the master wand is now the highest magic bonus weapon in the game.
They wouldn't do an auto ban random, but a more reasonable fear is that they will keep making randoms and the macroers will keep adapting to them and we'll eventually be playing the game Avoid-the-Random-Menaces-Scape.
Jagex should probably consider removing some older random events if they keep making more and the autoers keep adapting to them. Also I hear the autolog time has drastically decreased. I mean, come on... We don't got enough time to even entertain ourselves while we are doing stuff. (I like going to *site I shouldn't lead people to* while I fish/WC since it's so god dang boring).
