Interesting, I didn't know that the author of "The Anarchist's Cookbook" had disowned his work. But yes, I think especially for a traditionally published author it's nearly impossible to destroy your work. It seems easier on the Internet, but I think that's mostly an illusion. So many places a copy can be lurking...

I do tend to think that someone should consider their long-term plans before they post stories, rather than after. If privacy is the issue, that's what pseudonyms are for.

Thanks for your thoughts! :)
