Anyone who participates in social media via their real identity is just asking for trouble - and the TSA is not the biggest threat you need to worry about...I certainly don't need my employer or prospective employer digging through my online life, let alone any other unnecessary organizations.

The only "social media" site that anyone would use with their real identity is LinkedIn which should be nothing more than your resume highlights and professional connections. My Facebook account uses an assumed name and dummy email created for FB and I can still connect and interact with everyone I need to without FB and its systems knowing who I really am....and the government doesn't need to know either.
