I was on for about 5 minutes and logged in a town that me and 2 other friends of mine (ABParadigm and Starkiller1794) were working on. As soon as I logged on I continued where I left off making the zombie EXP grinder near our town.
I just started to work on it and I was banned for griefing. I talked to my two friends and they said their area wasn't protected so it shouldn't matter if I broke down blocks that they placed.
I think it was a misunderstanding of the server that I may have broken blocks that my friend placed as he is Zedling and I am not yet, as I only get on a few hours a day on MC and have only started playing on Zed a few days ago.
This may be the case and if it is i'll take precautions next time until I become a zedling myself if that is the case.
