Someone (who will not be named to protect the guilty) I had been in contact with on github sent me a slightly concerning message (outside of SE I may have a code stalker); they were using some of my code that I had put up for code review rather than using the hardened and improved version provided by the answerer.

It would be mostly defeating the point of CR for me to hide/modify the code that was reviewed. I am however considering adding a one line preface (or comment) saying something like:

Please use the improved code by xxxxx below (cc-by-sa 3.0 license) or the maintained latest *link* (MIT license) rather than the original here.

Other meta questions seem to strongly suggest it is fine to link to an external codebase but that was in the context about providing more information about a question. I have been told that editing your own question on SE after more than a couple hours have passed can attract downvotes to discourage people from doing that, but I'm not sure what to make of that information.

**Is my suggested preface suitable and appropriate or would it be best if I do nothing?**
