Well here is the deal as I see it, but since I don't work for LL I can't say for sure. Your a 14 year old girl and you lied about your age to get into adult second life. Which is againts their policy and a bannable offense. Sounds like you must have told someone in world and they turned you in, since as far as I know LL doesn't go around doing background checks on its 100,000 some members. Being under age in sl is no trivial thing or a laughing matter. Its an adult playground and no place for young children. Sure you say you were there for nothing adult and that is fine, but what if you are lieing about that? If you were there doing adult things and someone older got mixed up with you it could be very bad for them. In the U.S. depending on how things transpired they could go to Prison!! This is exactly why they have the teen grid and that is the one you should have joined from the get go.
Sounds to me like you got busted breaking the rules and they banned you. What exactly did the email say? Was it a ban or a suspension? My guess would be if you got banned for falsifying your age you might as well give up. Your banned, I hightly doubt sweet talking them will help. Saying "I am sorry I won't do it again and I will go the teen grid" probably won't do you much good. Sometimes in life you mess up and you just have to suffer the punishment.
My 16 year old wanted in second life too because he said the teen grid sucked. I talked to my boss in sl about it and she said no way not worth the risk. We run a racing sim, so it would be no big deal for him to be there. We just work on cars and drive around. No nudity or anything. But by letting him be there if he gets busted not only will he get banned. I will get banned as will his mother because we all share the same connection. As would my boss if they can prove she had knowledge he was underage. My girlfriend manages a club, I manage 3 sims and have 2 businesses in sl and my boss owns the three sims. That is a lot of risk to take just so my 16 year old can goof off on the computer. I would rather have him outside hanging out with friends anyway instead stuck in his room on a computer like me lol.
I hope your parents don't have businesses or responsibilities in sl as well. Because you may have ruined it for them.
I am trying to feel sorry for you, but can't seem to do it. You cheated and you got caught, sorry. Personally I am gald, the thought of 14 year old girls running around sl scares the crap out of me! I am wondering how you even got into these forums? I thought you had to be registered in sl to use them.
