You object to the banning rule and you say. "We're adults trying to sell our images to make a bit of money, it's not school!" and then you post "Giving advice, nurturing, helping, as opposed to plain banning them! An email pointing out where the contributor is going wrong, an invitation to ask questions as to where they're going wrong, making them feel valued. But no, stopping a contributor from uploading pics for 10 days is the way forward!!!" and that sounds exactly like your asking Alamy to be a school. Bottom line is do you want them to be spending time teaching people to take photos or out there selling your photo's ?
Cheers and gone
