I don't believe Feep was lying. His post seemed emotionally genuine to me. His fear and anger in his messages was consistent despite the things people were posting. Not once did he back down from his original story, which most people tend to do after a while if they post something false that gets them berated.
Some people have posted things of bad taste before, but I don't think Feep would troll or joke about what he saw. Can't say I am surprised at the inappropriate response from the forum though, it came without fail.
