i have run into automatic banning systems that will offer to ban my avatar because of hair, shoes, radar, AO, face light, mega poofer, dragon avatar, etc. All these items may contribute to lag I am told so I have been more prudent in their use. I usually will receive a warning and in most cases simply by complying with the owners wishes I have been reinstated. Loitering can also lead to a ban if the residents complain to the owner. I hope this is useful for you.
