I don't know man, that probably wasn't the best way to get a few more gamers on your facebook but I really disliked how most of them attacked him simply because he choose to post this on gaf off topic, he clearly meant no harm in doing so and I really don't see any harm in doing so. Don't like then don't comment on it, it's no reason to attack him.
These unwritten rules that people on forums are following these days can get ridiculous sometimes.
