Did ardy knights from 55-99. 3-4 hours at a time, twice a day. with the fatigue slider around 80%. i would also pause and click myself for a couple minutes when i was near by or go and do 2-3 barrows runs then come back.
But usually just played legit for 30 minutes then let it run for 3-4 hours. Never had any issues with it the entire time. not banned yet. highly recommend... just don't get greedy with the hours. have the breaks and afk timer reasonable.
Slow and steady wins the race. def just use w 302 and hide amongst everyone else. do not use splashing worlds bc if the knight needs reset you'll screw it up and get reported.
From my research this is a very very risky thing to bot, just try to take precautions... this script works very well
