I don't believe that for a minute--even though I'm not a coder. If those gold coins can be put under every member's rank, I seriously doubt Theymos (who is very intelligent and has a lot of resources) wouldn't be able to give members some sort of badge. Plus he did exactly that for the forum anniversary art contest winner if I'm not mistaken.
If I'm not wrong, for the art contest badges, he put them on manually. He can do it occasionally for a particular event, but I can't see Theymos doing it on a regular basis (unless he appoints a "badge giver", like he did for the "whitelisters").
Gold coins under our pseudos is an easily configurable feature of SMF. I think I have read (maybe in the Staff section) that Theymos reworked the reports page, so that's probably why it's not as easy to put those reporters badges and may require a lot of coding effort.
