What made the reference link unnecessary?

If you ask me, it's only necessary if it's word for word, or used as a source to confirm something. I don't ever recall the wiki citing rewards at all, let alone how to get certain things, like the recent Mabi Coin page. It's one of those "We've never done this, why should we start now" sort of deals. If it is on the page, we only need one citation, not multiples. Plus it's typically player confirmed, so the citation for that is pointless imo. Feel free to argue, but I'm just going with how the wiki always does things :s...

It originally only had one citation when it was first made, but that was removed.
