Having an official guidelines from theymos will be great but until then that doesn't mean we shouldn't make use of the trust system. We already have general accepted offends that are worth leaving negative feedback and positive feedbacks by DT and others. How about we stick to what we already have (which is working fine)  and when theymos finial decide to create those guidelines we adjust to them and change some of our feedbacks to neutral or maybe delete those that aren't a offends by his guidelines.

I did a infograph on possible reasons to leave or not leave a negative /postive feedback. Go check it out and leave your feedbacks via reply
