It is not SE's responsibility to host and archive anybody's junk. This is a curated library of data. I do not see any reason content this network has deemed unsuitable for publication should be dredged up for such a purpose.
If you want to use this site as a research resource it is certainly an appropriate venue for that and the content licence allows it, but you would need to ask questions the community approves of. This usually means you need to frame reasonably well thought out, respectful questions with suitable scope. The closure and -10 voting pattern and subsequent deletion are a pretty good indication that wasn't happening in this case.
