I have an old Facebook account that I want to get rid of. I posted some things that I shouldn't have posted, that might hurt my chances of getting a job in the future. I also heard of a Facebook app that lets you search the web for pictures of someone based on their Facebook profile pictures, and since it's conceivable that there might at some point be nude pictures of me on the web (among possibly other things), I don't want pictures of me on Facebook to serve as a launching point for such searches.
So I want to completely eradicate my Facebook. I know I'm not up against a team of forensic investigators or anything, just people Googling me, but I'm not familiar with what sorts of tools they have available. I was never that popular on Facebook, so I seriously doubt that anyone reposted anything I posted. My plan is to overwrite all of my posts with innocuous data and then delete each and every one of them individually before closing my account. As for my profile pictures, I will have to modify them before deleting them. The only way I can think of to do this is to crop them so my face is cropped out.
I need your help in defending myself against the snooping of others. Will my current plan be enough? What kinds of tools do they have? What are they capable of? Can they recover my profile pictures after I've deleted them, since they're still on the server? What is the best way to erase my presence from Facebook?
