Comb through it and "clean" if you need to. At very minimum, set your accounts to a privacy setting that only allows your friends to see it.
Be cautious about posts you make to others as well since they can be visible even if you intend for them not to be.
Whether you like it or not, your social media presence can put you under a microscope if someone has an axe to grind.
While it may feel like you are being censored, keep in mind the role that we play as educators and the standards that most people have for the people that come into contact with their children.
Also, understand that this standard is not necessarily the standard those same parents have for themselves...
