Continuing the discussion from Nice share counting visits from within the forum?:
As with mcwumbly in that topic, I have badges (both here and on SitePoint) for posts I don’t recall sharing. One (on SitePoint) I know I linked to from within the same topic, but I can’t imagine I would ever have linked to it from elsewhere. The posts are not linked from other topics on the same forum (as there is no link information back beside these posts). It’s possible that I’ve linked between SitePoint and Meta (and forgotten about it), but again, that seems unlikely for some of these posts.
Which is a convoluted way of asking: what is the criteria used for awarding these badges?
