Why isn't it a good idea to share personal information with someone you've met online?

personal information you share online can be retained and used for ill ends. When you share little tidbits of information, these little bits can be pieced together to find out your age, where you live, when you are home and not home, and other pieces of information you may never give away knowingly.

So to prevent this, the best course is to avoid sharing any personal information.
