The line of privacy

Lately, I read a blog post where a mom found her child's photo on someone else's page (and with a cocaine background!). It's got me thinking about privacy and if I'm protecting my children. I've already posted a copyright statement on my blog, but I realize that not all people respect that. I've also added code so that my photos cannot be right-clicked (and saved or printed). I have to make the extra effort to delete code within each post so that my photos aren't clickable (to enlarge) because then my photos can be right-clicked. If you know how to add a single code to do this, PLEASE tell me. So, I think I've done as much as I can to protect mylsef in that area. The fact that I have pics on facebook has me confused about all my efforts. I need to look at my privacy settings and make some decisions there. I want to share pics with old friends and family, especially those that don't see my kids often. However, I don't want creepy Joe Shmo looking at pics of my kids.
But, my biggest concern right now is the fact that I use my kid's names on my blog. I thought about going back through all my posts and changing their names to initials or a nickname. That would take a long time, so I'm not sure if it's worth the effort. Most blogs I read include their kid's names. But when I came across a few that don't, I wished I had done that all along. However, it's not like I have a huge following and tons of strangers are reading my blog. I decided to sign up for Google Analytics to see what's going on with my blog and maybe that will help me decide if I need to beef up security. I don't want my blog to be impersonal, but I would hate for using their names to end up being a horrible mistake 10 years from now. Lots to think about and learn about.
Sorry for such a boring post. I'm just thinking aloud. If you have any opinions or suggestions, please share them.
