As long as Facebook does not tell other people my password for Facebook or my e-mail to non-friends I'm ok.
I don't post my phone number, photos or video I don't want people to see online, address, or any info I don't want to make public on any website unless I have to like filling out the shipping form, so an Ebayer can send me my purchase.
I agree. It is not a good idea to post sexy photos with your real name and address. You can invite uninvited guests to your house like sex offenders and other unwanted people.
