alt Hacker NewsTo hopefully save some here the risk of an embarrassing redaction mistake:
Redaction should be done by deleting the content from the media AND THEN adding decoration you want to indicate the material was removed.
If you do things any other way you're liable to end up with something like the attempt on the site where the email might as well have been highlighted instead.
Can also be useful information to have if you want to give the appearance of having diligently redacted without doing too much to protect some asshole. IMO if the author of that email wanted to protect their anonymity and employability they should have used a throwaway, Don is doing them an undeserved service by even half-assedly blocking it out.
