I get the frustration, but I'm not in sync with calling people out on this one and condemning them for it. That may be because this is something I have done, and as such, it is a little difficult to be neutral on this one.

There can be any number of valid reasons behind de-archiving stories and/or and blocking robots. Some of that is just routine website maintenance.

I pulled several stories down from my website several months ago. Some time later, I got a few emailed complaints about my site not working because people would click on links on the Wayback version of the fiction menu and it would direct them to pages no longer available on my personal site. So I blocked the Wayback Machine from archiving pages at my website to avoid that confusion.

I fail to see the comparison between the above actions and publicly destroying valuable copies of historic literature in a statement against the decadence of literacy. As flattering as it would be to view my work that way, that's really not an accurate view of it. This is more boxing up old stories that are no longer relevant or useful to the purpose of the archive itself. They aren’t completely gone, but I do hope they'll be forgotten.
