Why should they? The comments are handy years on. Use a pseudonym?
Usually doxxing those nicks wouldn't result in financial compensation, but lots of legal trouble.
What you want is fringe and confusion to me, especially in this context. You control your nick and your comments are attributed to it.
If somebody else uses your comments for something useful, they can cite your nick.
If you do not wish your User Content to be displayed, I recommend that you do not upload it to the site.
