I just asked him that as well, he says he does not remember exactly the words he used but asked them about the use of the Angels in the promo art (with Dante pointing his fingers like a gun at one Angel's head— that art) and what kind of messages they were trying to give with it. Then he says he couldn't log in because his account was suspended.
I suspect that came off to NT staff as "this art is tacky!" and they suspended him. Even so, a forum run professionally that is supposedly for discussion of more than one viewpoint(?) should not ban someone simply for questioning the art/imagery being used.
Tameem shouldn't respond to fans, basically. Or not respond to negative comments. It makes him look just as bitchy and unprofessional to do so. It might not be fair, but it's the way you are supposed to act as a professional. A politican for example is meant to stick to their guns and not respond personally or on a personal level even when goaded to by, say, a protester or member of the public. You are meant to show decorum as a 'figure' for something, not descend to the level of the mob. But Tameem seems to be doing so and he's lost quite a bit of respect for that it seems. He's not a politician he's a designer, but even artists are held to this standard... writers, artists and designers will come to be seen as unprofessional if they rise to negative bait. As an artist you must endure the criticism of your work because it will always be there, and it's best to do it with good grace and ignore the haters, or even better just respond civilly and kindly to them, showing yourself to be above any nastiness or bitterness. It shuts them down faster and makes you look far better than someone who uses sarcasm as a response, etc.
