I don't think you have to be a paranoid person to use caution on the internet. The reality is that there are a lot of ways that you can get hurt by unscrupulous people. When my kids were little as a family we made an internet agreement. We all chose pen names to use on the internet (LOL my real name is not Anna) and it was one way that we taught out kids to be safe. No personal information was ever given out and we have always been fine. There are a few folks here the I have PMed and given out more information and that is a risk that you are taking. It really is a matter of deciding what kind of life you want to have. I just don't want to live a fearful life I also don't want to be so taken advantage of.
