John,
We (usually the team in Registrant Services, but sometimes in the Legal Depatment) will opt in domain names which aren't eligable to be opted out. We do this whenever we notice such names, without any favour or prejudice, because it's our job to ensure everyone works by our Ts & Cs wherever we can.
If someone asks us for contact details for a registrant who shouldn't be opted out, then we opt them in, allowing the requestor to see the details (as they should be able to anyway) rather than wasting time sending the details to them.
If we opt in a registration then if time allows we'll check similar registrations to see if we can sort a load at the same time.
As I say, here in legal we do all this if we happen to notice and if we have time. There's little doubt that, because domainers sometimes like to bring one another's registrations to our attention, you being on here might mean we notice (are told about) more of your opt-outs.
If you'd like to know more about your particular domains and why they were opted in, please give me a call.
