Thanks! And totally. Blurring a sensitive photo is not protection. And even other methods that seem to avoid the issues blurring has, like blotting out someone's face with an opaque brush, can still leave more information than you'd like (e.g. metadata in the image file, details of a person's clothing (which can be identifying), etc). Best practice is to not take photos of people without permission and not release them at all if they contain information you don't want to share.
