Yes, OP talked about bots, just like everybody else here, but very few talk about punishing gold buyers, meaning many would be guildless or in barren guild one day the log in.
Yes, bots are a plague to the game, but in a way I can understand bot owners, some of them even make living of botting and gold selling.
For me, much worse are gold buyers who get unfair advantage in game over others and then even hypocritically brag about their in-game success and parses, becoming heroes for other players.
