SolvedPlease Explain: New Fame Farm Exploit

Don't really care about getting fame using the exploit just have a few questions.
1. Why does the exploit cause extreme lag
2. how does this exploit get you so much fame
3. how does it work (no im not asking for a tutorial on how to do this(although i would like ojnhe ;D)wondering how this gets so much fame and what it does to the server)
if anyone can answer my questions it would be really nice

Moved to help requests.

1. Your computer's bad if it causes lag, any big mob should lag your computer a bit though.
2. Esentially lesser gods are used as spawners. They ultimately spawn 4-5 tiny minions worth 40+ exp per so 200 per spawn. With enough spawners you have a steady steam of minions to farm while safe inside a castle or something.
3. Nillys/kRelay + Ignore Mobs. Ignore the lesser gods, there's a list will all boss IDs. Turn on autoaim with a multi or something after dragging some outside of a Cyclops Castle or Ghost King area. Sit back and relax.
