Unfortunately yes. There are a few blights on the Lost fandom, RL shipping being one of them. It happens everywhere, I guess. Some fan(atics) want to take it too far (stalking the set, stalking actors, shipping them as RL couples), and get skeery.

Those are the dark corners of fandom that it's best to just back sloooooowly away from, keeping your hands visible and making no eye contact.
