About other kinds of bots, they aren't around because they are hard to make, and much harder to maintain. Standard reverse engineering (disassembler, standard debugger), which is what most people (or at least myself) are used to, is useless with runescape because the client is not compiled into machine code but into java's bytecode. If the Runescape client was always the same, in some time a bot could probably be made nonetheless. However, Runescape changes each week, in a way specifically designed to fight possible bots. So it gets much harder.
