"Good reason" to get access to zone files

[DomainEmpire.com]

What's a good reason I should mention in the application form in order to get access to Zone Files ? I don't have a clear reason to give, I need them (just once, not interested in updates) to make some personal studies over these lists, nothing special and not a "good reason" to justify my request probably

I'd apply for both (com/net) & (org) ... Is there someone who already have a recent copy of the same (I suppose few Gb of data) and who'd share them with me against a small fee or in exchange of another courtesy from my part ?

Thanks again for helping.
