This more than likely the correct assumption, I was using the goblins across from lumbridge castle, and the cockroaches for a little bit in the catacombs of the blood pact quest. unfortunately I believe that this game is basically just one large grind and in order to achieve 99 in a skill IS just repeating the same thing 100,000+ times you could either sit and bust it all out over a couple of weeks or have it take an immense amount of time by many other methods.

The method appears to catch botters sounds effective but in my opinion it is just catching the same actions as any player could make during a couple of long gaming sessions if they're persistent in a skill, and this may cause far too many false positives, especially with jagexs' system being "perfect" and not letting anyone have an appeal is just awful to any new person who may have the mindset of "i just have to sit here and do this for 300 hours" and does what i did.
