I never get rid of anything, unless it falls victim to tech failure. I've kept the first website I ever designed, the first poems I've ever written, the portfolio I painstakingly crafted to get into art school - all of it safe and sound, backed up on hard drives.
I started blogging because I wanted to inspire women and now the thing I think about the most when posting outfit photos is "How likely are these photos to turn on some creepy guy and make him desire to tell me about it?"
Don’t get me wrong -- I (mostly) support guidelines for Internet communities, such as ones that minimize things like underage porn and hate speech. But few social media sites have guidelines that are clear, consistent, and nuanced enough to deal with all variations of expression.
