On reddit, I often see comments about upcoming games that really strike me as astroturfing... It's mainly that it makes so much sense for manufacturers to do this (word of mouth is more compelling than "advertising"), that I can't imagine them not doing it. So when a post is just emptily positive in a generic way ("Really looking forward to this!"), with no content to suggest it's not astroturfing, I assume it is. I think one way it can be given away is not from an individual comment, but in the context of all the comments on that story. But if it's done well, it's impossible to distinguish.
