Postanou you are also an example of poor admin. Firstly you should not assume 8 hours in game is 8 hours of gameplay, even if it was 8 hours of gameplay you also should not assume a player would know what to do. Also Mounting a horse in a players base is not stealing is it?
Do you go to someone's home and sit on their couch and have them accuse you of stealing their couch? Do you understand that its a new player's natural instinct to interact with objects they haven't seen before.
"Plus you demonstated enough know how in game to know the difference, so your excuse you did not know does not fly." Thats very arbitrary statement with absolute no evidence. Both of you admins should feel ashamed of yourselves, very disappointing.
I recommend you read some book on management and administration, because even in a game, you guys are struggling.
