Supposing a poster alternated between being caring and considerate one day and then became vicious, foul and so abusive that it made some people feel physically sick with the sheer awfulness of what was posted? Then suppose you discovered that the poster concerned was actually taking medication for schizophrenia?
What are we supposed to do? Forget the bad days because the person concerned probably can't actually help the way that they're acting?
I'm not trying to make a point here. Some ex's do have serious mental health issues. Do we have some sort of obligation to assist them?
As long as we are just talking about this board, and not real life, I personally would be inclined to make some allowances. We don't have to worry about being physically attacked. Knowing that a person had a serious mental problem would make it easier for me to dismiss the crappy stuff they might say, maybe even give some of the love and care that I would be too afraid to give in in person. I mean, I felt compassion for Natalienlieu. Maybe she was just a troll (hell, maybe she was a he, I don't know), but I felt she was an okay person who suddenly got into a sad, bad place. She really seemed to go a bit wonky. If I knew that she was, for example, a diagnosed schizophrenic I might have just wanted to say, hey, calm down, take your meds, you're doing that thing you do and you know you'll be sorry later.
