You're new here, so you're not aware of the issues we had years ago when anyone could upload and we got a lot of crap-looking scans from members. Some people may be fine with that, and that kind of stuff is fine for archive.org, but we're different. Content owners know we exist and almost all of them leave us alone. Part of that is because we represent their content well. If Steve Harris comes along again and sees nice looking scans of GamePro and Game Players, but sees that a bunch of EGMs are terrible quality scans, he might take exception to that and instead of asking if he could use our scans for a project, he could tell us t take them down.
On top of that, Scarred Sun wouldn't be re-uploading everything. The would upload one to some file sharing site. If it's good, one of us would upload it here for him. Then he could upload the rest. You're assuming he already uploaded them somewhere.
He can definitely upload them to Archive, and we can link to them, though if those scans get removed, we now have a bunch of broken links.
