I know when FB recommends people I might know to friend and they were people I knew I was confused at first how FB would know that I know them since I have everything blocked on facebook and don't friend anyone and only play my few games on there. I then realized all the people they suggested I might want to friend were in my address book on the computer. That is the only way FB could have suggested those people. Heck on my smart phone when my addresses got transferred over from my basic talk phone all of a sudden a few of my contacts had pictures with them so it must have synched with my online address book and gathered the photos from their facebook since they were used in their facebook profile photo. Funny how all this stuff works these days. Mary

If your settings are correct the only people that can see your profile page are the ones you have accepted as "friends" If they are set correctly only minimal information is made public. You can also set it up so that your name won't be found on FB when someone does a search for you. Anne

If I hide a friend, does that also prevent others from seeing their posts on my Wall?

Last week I researched something similar and this came up in one of the search results. I don't think it can be done. I've noticed that you cannot delete a post that you started, either. But if you suspend or remove your account, the comments disappear, which is a drastic solution. Maybe your relatives are finding the updates from your Wall. Click on your profile to see if they're there. If so then you can delete them. Then get in the habit of deleting your comments there immediately after you post something in a group.
