Probably influenced by other comments in the thread I interpreted "And even that isn't save [sic]" in your comment above to mean the direct URL in some fashion wasn't "safe" in the sense that it could point to nefarious code. I presume now your intended meaning is that even the direct URL you gave might not be a reliable ("safe") way of accessing the code.

I meant to say that we can't reliably check all (subtle) edits to a post.

Even if the authors are reliable, their accounts could be hacked, especially after them being inactive for a decade.

That's why such links should better point to immutable posts, like from anonymous monks.

For safety, I disabled Len's login and mangled his pw recovery email. He hasn't been here in years, and is probably unlikely to return, but if he does, we can easily reenable his login, and advise him not to mess with spiraling quine. :-)
