It's an interesting analogy. I don't think I would make the FBI tip. and I would be frustrated with other people who did. 

However, there is quite a but more history here than just a teenager discovering an old gun. The spam debate has been ongoing for many years. I personally have been writing about it for at least three years. I have had what feel like endless twitter conversations with Chris guida, dathon, and Luke. I organized an AMA for mechanic here SN so he could present his viewpoint. I don't think I'm being uncharitable.

if some teenager posts photos of how they found an old unused firearm and have polished it and restored it to working order, and all the local gun nuts show up with enthusiastic praise for the well-regulated militia's newest member, do you immediately send an anonymous FBI tip about someone planning a school shooting?
