> Aldi had great success posting "hauls" until they were caught astroturfing.

Is there a decent rundown of this anywhere? I tried a couple of google searches but didn't find much.

(I often get the feeling this is being done by various companies, especially on Reddit, but I find it hard to distinguish between astroturfing and sincere consumerism. Especially when they are probably working in combination: astroturfing to set the tone, then genuine community members jumping on the bandwagon and acting as unwitting accomplices. So I'm interested to read case studies wherever it has provably happened.)
