What do you think is happening behind the scenes?

Runescape has no hacks or dupes.

There was a massive bot problem, one that Maple could only dream of having, and may have even exceeded WoW's botting porblems. Then Jagex was like "hey guys we finally got a fix for this," and launched a bot nuke that trampled all the bots right then and there.

Of course, a second bot nuke was planned shortly thereafter. With good reason, because many bots are reappearing as more and more of them find ways around the first bot nuke.

Bot nuke? I haven't played RS in ages, I remember when I used to be the only human being there mining and fishing. If things have changed since then, I want to know what exactly they did.
