~~~ if there is no mention in the subject or body of the post.

Let's say someone included a scan a while back of a chip with graphis: "ABX CLUB" without actually spelling it out within the post... and a year later someone needs to find that post to match it with what they believe is the ID requested...

Thus the reason why it is so helpful in include what all the chip reads in the post... Though now we have the Gallery Index which is helpful.
