People act in the limits of consequence, and the same goes for companies and their products and services. Accountability helps making the limits clearer and narrower.

Some times, sites appear hoping to help consumers in such regard, like Reclame Aqui, an old Brazilian review site that grew into being an alternative support medium, companies hating having a poor ratio of resolved issues there, and Consumer Rights Wiki, seeking to document cases of consumer exploitation. The former already having a positive effect, and the latter that though I haven't seen tangible effects, could have too.

But it leads me to think, are there other such cases that have already had positive effects, or that could have, be them regional or otherwise?
