Jagex would never mass ban rwters and botters again. Look at the loss they will make with all the lost memberships...
Oh my friend, how terribly mistaken you are. Let me bring up a past few events for those of you who don't know.
I wasn't around for the mass ban that came from AR's detectable packet-sending macro, but I everywhere I read it was a mass number of accounts banned compared to total accounts.
Later on, still during the RSC era, a new wave of bots hit the scene, STS, SBot, RSD, and quite a few other low-time bots. All very detectable compared to our advancements now days, but because of how easy they were to create and use they were abused, to say the least. I was around for this ban, I took some screenshots (on my old computer) of a huge amount of people standing still in small areas around Runescape; usually around mining & fishing areas. They remained motionless for a few days before Jagex announced banning these accounts.
Again, these banned accounts made up a huge percentage of all accounts. Thought, by legit players, to have shot themselves in the foot from the profit loss of banning the accounts, Jagex had no concern, and thus later on the release of Runescape 2 beta. Drawing in more and more players, it's like the mass bans never happened and they were, once again, drawing in lots of profit.
(Still through this whole time, SCAR and the SRL team ran in the shadows, but this is besides the point.

)
Eventually Aryan (or was KYAB first?) was born, marking the
true beginning of the RS2 botting scene. (I'm not sure if this was the last of the packet bots or simply ran via a heavily modified client, need to ask Benland

) Again, this bot spread like a fire through it's easy-to-use API and at that time Jagex did not obfuscate their client, making things very simple. The biggest ban so far resulted from Aryan-users, a severe hit in the user-base of Runescape. This was the reason we now have obfuscated clients. But even after the huge loss, the RS population grew yet again, as expected.
Aryan was the last
real mass ban so far, but who know's what's to come. As you can see, there's always a period where bots flood Runescape and a mass ban follows, yet every single time the population not only returns to normal, but exceeds the previous user-base.
It's obvious the people who say "Yeah, a mass ban is going to kill Runescape, they'll lose so much money" actually only
want that to happen, they're the ones who, more than likely, believe they'll be one of the accounts banned. Out of spite, they want Jagex to lose profit from a mass ban, but as history shows, that won't stop them.
