You should remove old posts & comments from every site you post to on a regular basis. There is no reason for those pictures from 2007 being on Facebook. Your old Twitter comments from 2011 might bit you in the ass in a few years. Nobody in their right mind is looking at your 2014 Instagram posts and you don’t want people out of their right mind seeing those. Why should that comment about Obamas election still be available for the world? Just nuke your old stuff on a regular basis - nobody looks at it and if people are searching through your old posts, they want to harm you.
