Beats me. I found Iban to be very reasonable and intelligent. He got to the point where he disregarded the forum, which doesn't surprise me given the largely baseless anger people had towards him.
I think this was another drama case where people worked themselves up over something small Iban did, then blamed Iban for being some terrible person he wasn't.
If he does play still, don't expect anybody to ever find out about it. I'm not surprised he is gone given how badly people treated him.
