I fixed the link and stated:
Data should not be malformed, if sensitive then please remove it.
And this sums up my feelings on the issue.
When / if the user returns and wishes to act, this is the action I would suggest. Expecting users to manipulate post stuff (other than the obvious issue to solve) isn't conducive to getting an answer anyway.
Perhaps some official input may be required to avoid this spiralling into any kind of edit war.
Reading Arjan's comment on Justin's answer makes a lot of sense here too:
If the OP doesn't want the URL from being indexed, then the OP
apparently is sure that it will change soon, or be gone altogether.
That makes it a bad reference for the question to start with: what
about tomorrow's visitors?
Ideally the OP would have made an SSCCE with, say, jsFiddle or something similar which could facilitate their needs; obviously the longevity of those links could well be limited as well, the links will eventually die instead of radically change as the days go by. This just stands to reason that such an example on an external link ought to be fully reproduced (in its already minimal form) in the original post.
This doesn't justify abusing linkage.
