I do not post my picture, or any real personal information on Facebook. I cannot believe the number of people who post every time they take a dump....
I do have pictures of me posted up on Facebook, but I RARELY use them as profile pics, and then only briefly.
Also it is a safe bet that not everything I have posted in my profile info is "accurate". I'll leave it to the gub'mint data mining software to determine where I'm telling the truth and where I'm bullshitting.
Finally, I keep personal references to my politics, religious beliefs and any causes I may or may not affiliate with deliberately vague, and I NEVER, EVER click <like> on whatever cause du jour is floating around on the wall. Facebook is also not a place to find me discussing topics which may compromise SHTF/EOTWAWKI OPSEC. Again, I'll leave it to the data miners to figure out what I might have and what I don't and where I might be when the jackboots start goose-stepping and the men in black start knockin'.
I took my page down this fall -- someone hacked into it and started sending messages out to a few people on my friends list so I shut it down fast :hammer:
The more I read this thread, the less I think I'll ever facebook.
