Uh.. I ran the same script as you did... and im pretty sure you had the wrong settings and hides. I'm still able to make 200k/hour or worse case 150k/hour even at the most shitty hides.. So your claim for 50k/hour, it doesn't seem possible? Not trying to side anyone. Just base on my profit calculation lol. Lets say a blue hide gives you 147 GP per hide profit. Making 100 hides take less than maybe 10 mins? Pretty sure it still gets you at least 130k/hour.
Also to your claim of getting yourself banned, Yeah tanning is HIGH ban rate. Even if you bot 10mins, Jagex bans you.
