People like to post things on their Facebook wall but sometimes they post the wrong things that may or can offend people in a way. I feel if people want to put things on their profile then go ahead but if bad things happen to them, it's their own fault really.
If people want to have fun on Facebook or any social software then they should only add their friends and keep it Private.
People put photos of their family on it to keep memories, that's why I have photos on my facebook so i don't loose them and If I want to look back on them, I can just go on my facebook and see them.
Am done ranting for a bit
