I hate bots, runescape back in the day made me hate bots, hackers in FPS games made me hate Aimbotters...Hate...bots
But to prove a point, why make a complicated script when you can use an auto clicker. Easy to watch a movie/show while having the auto clicker doing in your game. To give a visual example:

Turn on the sifting thing, place water right under your, feet watch video as the auto clicker auto clicks.
You can see when someone messages too. Especially someone new via PM, can also hear when someone messages you.
So you cannot prove someone is botting. and I am SURE I helped all the knuckle draggers with this one because I doubt they thought of something so simply until I brought it up...
P.S I made sure to have a funny scene in the video playing just for the amsement of the picture, and yes that video is great.
