I don't think that particular one would be very appropriate - personally at least. Only because then it arouses the question of "Who did you nominate?" and "If you nominated someone, why didn't you nominate me?" You know what I mean? That and it does go off a 100% faith basis.
I think if we're also going to be doing badges it should be for things such as the following:
Liked Character Fans;
Or people things participate in that aren't the Dokuga Awards;
I think of badges as boyscout and girl-scout badges.
You gain badge as you do something.
If you've made a stamp then you get a stamp maker badge.
If you like Bankotsu you get a Bankotsu fan badge. You know what I mean?The below are just ideas I made real quick I and I haven't gone back to make them pretty.
