I have definitely put things online that I would not want selection committees to get their eyes on. I have a very "chameleon" personality type, which translates into many different selves in many different settings and circumstances. That will be true of me at any age and as an introverted homebody who is more comfortable and witty when I type than when I'm face to face in a group, I gain a great deal of value and enjoyment from my online interactions. I'm not willing to edit myself and put on my professional face in all internet interactions for a lifetime for the sake of these types of short circumstances.
So, I lock things down to the best of my ability at times like these and hope for the best. :fingerscrossed: Unless you've already recieved rejections to 100% of your sites, which I doubt, you could lock things down more now. Couldn't hurt. Unless you have lots of professionally relevant or personally charming posts. Then, I guess it could, lol.
