Memory Alpha has done the same. We also decided against "Badges" and "Achievements" since they work counter to the community that we have fostered over the years since MA was created (pre-dating Wikia no less).

I too will be taking this approach if these things are forcibly implemented on Memory Alpha, and encouraging the same of all of our administrators.
