"Badge of Honor" seems like a fine enough reason for a token... but who knows? 

I guess I have always thought SMTs and other "private tokens" were a bit questionable because WHAT exactly gives them "value?" Seems "value" would be derived from having something — *anything* — be tradeable for *"real life goods and services"* in some way. 

In the case of the engagement leagues we're all a somewhat *competitive* bunch (I think...) so "value" of a token can perhaps best be measured as some type of "brownie points" for doing specific tasks, and (eventually) take on a *small* monetary value as somehow "exchangeable" for upvotes. Or something.

Just thinking out loud, really...
