I guess the answer is "don't mess with your old site", but that's also impractical.
And I'm sorry, but if it's my site, then it's my site. I reserve the right to mess about with it endlessly. Including taking down a post for whatever reason I like.
I'm sorry if that conflicts with someone else's need for everything to stay the same but it's my site.
Also, if you're linking to my article, and I decide to remove said article, then surely that's my right? It's my article. Your right to not have a dead link doesn't supercede my right to withdraw a previous publication, surely?
