How do you capitalize “spam”?

Question

Is it legitimate to put "spam" (the junk email kind, not the trademarked meat) in all caps?

An example I've recently read is

Please read before flagging as SPAM (a reminder from your moderators) – ends Sep 5

Answer 1

In ordinary formal writing, spam should not be capitalized. In your example, the author could have capitalized it for emphasis or because it reflects the way it is written in the user interface.
