Imo a simple macro program will work. (Shhhh) I built a grinder at my /home. I had killaura on and /god on. I set my /back at the gunpowder selling shop. So after about 8 minutes of being at /home grinding, 'I' would /back and spam right click to sell. After a minute, I would /home and rinse and repeat. Earned millions haha..... (60k/ hour) However, there was a flaw and I stop using it due to the fact that it caused lag to the server. My character bugged out and my killaura stopped. Resulting in mobs spawning endlessly ( I inherited someone's formula to make the best grinder) This made the server's TPS to be 3 and made it so laggy to the point of being unable to move and Clag cannot clear the entities. So I got quite some flame and anger and cyp came and shut it down. So heh...... And a new hidden rule came , no afk farming/grinding in org.
Agreed, the easiest way would be to use a macro program that lets you record your clicks and keyboard entries and repeat them in a loop, but be careful don't end up dead in the void... or worse... like aloha and cause a new rule to be made
