Yes, that happens. The longer EFLI and Harry remain 'missing', the more we will come to 'assume the worst' but, in general, such 'conclusions' are not always going to be correct.
In my time, when a forum/whatever has become too unpleasant/ridiculous/whatever, I have simply 'walked away', with no comment or warning, never to be seen in the place ever again - and those there might well 'think the worst'.
However, having said that, I don't think there is any reason (in fact, quite the contrary) to think that either EFLI or Harry would have had any reason to do that - i.e. I would think it extremely unlikely that either of them would just 'walk away' with no comment, explanation or 'warning'.
