I thinking archiving is important, archive.org is great, and I'm proud of what little contribution I've made to date.

Someone recently pointed out that an upload I had made is now inaccessible. In it's place is a short message: this item is unavailable due to issues with its content. What issues are not made clear.

I've never been contacted by archive.org about this, not even to be admonished, should they have felt that to be necessary. I've tried contacting them to find out what the issues are but have heard nothing back.

It's worth remembering: Just because it's available now, even on archive.org, doesn't mean it will be Tomorrow!
