I feel as though this is simply a case of someone who is double logging. His main is in the bg on the horde side and wants an easy win. He just BoP's the fc in their fr so the other team can return easily and get a cap. This is probably the worst case of multi-faction abuse I've seen. As everyone knows, it's extremely common for horde to ghost queue bgs so they can get their main in. This leaves alliance short players leading to more alliance losses leading to more alliance leaving the server or switching to the horde side resulting in longer queues for everyone and more factional abuse.
I suggest the administration disallows multiple accounts on this server and doesn't allow cross faction toons on the same account. I realize people will find ways around this by using proxys or what have you, but at least it won't be a super simple thing to do and may reduce the amount of abuse a little.
As for Vrobi, I think administration should deal with him on this infraction. It completely destroys the game for everyone when someone does something like this. IMO, this is as bad as a hacker teleporting back and forth to the FR.
