Great question, artist and thanks so much to Doc John for answering it. I haven't had a chance to read Wittesea's and Jo55's links but I'm going there next. Very interesting topic and I think any of us who participate in an online forum or even one forum in particular have seen this happen unfortunately. I've always thought myself that it was a way of seeking attention. Even though it's not always easy, I think the best thing is to try to ignore them because otherwise we're giving them encouragement.
