Make it hide auto-delete or at least hide from everyone else by default after a while, viewable only by friends, illegal to consider in any school disciplinary action or admissions process or job interview. I guess he's talking specifically about children's posts here, but I definitely want to know if a kid is threatening to shoot up a school or engaging in online bullying. I also want to know if a potential hire is a Neo-Nazi or a Qtard.
