I've been doing a bit of (very careful to be polite) scraping of Wayback to get archives of now-offline sites, so I hope this won't cause any significant issues for me. I did contact them beforehand to request a direct copy of the sites/networks required (which I believe they offered at some point) but unfortunately received no reply.
