How are you determining that they have the same owner?

There is a lot of shared infrastructure between archive.today and btdig.com. For example, btdig is often hosted on the same IP as AT. The sites engage in the same behavior. Both sites engaged in DDoS attacks against gyrovague.com earlier this year. In June, both sites redirected Wikipedia users to Tehran Times. In July, both sites started redirecting to advertising sites. I have other evidence I can't share publicly, but the public evidence alone is sufficient to confirm a link.

Interesting. I didn't know that, thank you.
