Thanks for the explanation. I didn't know about the peering being only for new content. I was thinking of simply downloading the full feed of another provider and adding it to their own (automatically, somehow). But if there is small print avoiding that, then it can't be done.

I was thinking about the storage cost only.

By peering older days from the usenet itself? Doing it from nzbs could also be something. There is a lot of old content at many indexers.

The major reason I feel trapped to Omicron is that I enjoy (no so much) cult content from every possible place and language. And a big part of it is 2008~2013.

I see all the NewsDemon advertising and way to do business and I feel sad to be unable to just drop omicron for my use case.

Thanks for answering and for the proposed solutions.

About the DHCP backtrace, that is the (standard) procedure being avoided. I don't think it's paranoid, it's just how it already works.
