I have a friend who sometimes removes comments from his Facebook posts that are slightly off-topic or detracting from the point of his post where the post is intended to boost his reputation and kudos in a certain topic.
It's not egotistical or egocentric or really narcissistic as it can be seen as a valid thing to do, but it's in contrast to what others do, and allow conversations to flow freely and even go off-topic and don't remove any comments unless of course they are offensive or insulting.
So, what would be the word to call this person, someone who is overly self-conscious about and overly nurtures and maintains their online presence/image/persona?
