@NewK, I am well aware. Artificial lag is a rule break. But, I haven't used any such feature. However, At that moment, My net was shared to one of my family member. It was being used in a handset.
This is the very definition of intentionally playing with lag. Your lag may not have been artificial however you did intentionally play knowing your net is under heavy traffic by your household.
You kept rejoining instead of fixing it/waiting it out and now you've faced a tempban because of it, perhaps you're not aware of it but this is ruining the fun for other players.
