The question is how do you deal with someone throwing their dollies out of the pram? Answer: club together and make use of the revenge button. There is always going to be players who for some reason decide to "punish" their team mates 'cos they didn't get their last Rolo. Game developers rarely intervene since the problem is usually caused a tiny minority and doesn't effect the game as a whole.
These sort of disputes are commonplace because online gaming can inflame emotions, often resulting in scenarios the OP described. You really can't expect the game developers to solve this issue when much more important issues (in the grand scheme of things) need their attention. That doesn't mean it isn't a problem to you guys and everyone sympathises because most of us have been there ourselves, it's just something you as a guild will have to deal with.
