Multi-Box clarification

[Lucia Moonglow]

I understand that the letter of the rules strictly states that you cannot control two characters at the same time, but I have heard rumors and want to have those put to rest one way or another so I don't end up getting banned if I decide to do it myself.

As I understand it, multiboxing is forbidden because it harms the server population, since people that want to do it don't have to group and/or socialize. I am very happy about this rule, as I hate multiboxing and have left servers in the past because I felt like I was forced to in order to get anywhere.

However, I have heard rumors here and there that you are permitted to log a second character in for the purposes of muling or transferring gear between characters because it doesn't negatively impact grouping or the server's social structure. This sounds shaky to me, but I would like to hear from a GM or someone else in charge on the matter so I can know the official stance.

So can someone official please clarify this rumor for me?
