Iv been banned because of my sister

[sneak417]

I recently let my sister play my minecraft on this server on 8/14/15 that night and early morning as well as on the following day after playing on the server my self. Soon my sister came to me telling me that she lost connection to the server. I red why and it says griefing -st. I asked her what she's been doing and she says she's been just running around and checking out sites and occasionally collect stuff and then she said she fell into a cave and there was beacons in it. She says she lost connection to the game soon after. please let me back in. she wont be on my pc anymore even if, whatever she did, she most likely didn't even know any better being only 7 years old.
