Briefly: To help promote their upcoming found footage Sci-Fi thriller Apollo 18, Dimension Films sponsored an IAmA Reddit thread with UFOlogist Stan Friedman, where you could ask him questions related to the film or UFOs. However, the thread quickly got ugly with users attacking Friedman for being part of a promotion, calling him a fraud, and much more. This is one of the negative aspects of viral marketing, since the audience becomes part of it, and you can’t control how they will react. Apollo 18 opens in theaters on September 2nd.
