I deleted a bunch if photos from my Facebook because they made me embarrassed. I was always very toned down on Facebook when I was 15 and 16 though, compared to how I was on anonymous imageboards. Everything I posted in my name was very calculated and deliberate.
Now I just use Facebook to vent and post anime babes for future reference. An average post is just a semi-nude anime girl with some ranting nonsense that I feel strongly about, because my life is boring and I don't have any friends.
