If they were able to identify him based on things he knowingly posted publicy to Reddit, couldn't anyone who cares already find out who he is?The apology came after CNN's KFile identified the man behind "HanA**holeSolo." Using identifying information that "HanA**holeSolo" posted on Reddit, KFile was able to determine key biographical details, to find the man's name using a Facebook search and ultimately corroborate details he had made available on Reddit.
If he wanted to remain anonymous he wouldn't have disclosed enough personal information that could link his anonymous reddit account to his public facebook account. If he has since deleted the trail that can lead to his facebook account, and CNN is still threatening to release info if he goes back to being an asshole then that's pretty reprehensible.
Really surprised CNN even went through the trouble of finding him and starting this mess; memes control the world now I guess.
