You are correct nothing depend on this "vote" and it is meaningless except you seem to be getting your feelings hurt and wish therefore to make it harder for people to vote your comments down.
The fact that for some reason your feelings are being hurt is hardly enough of a reason to show every one who had voted on a posting in my opinion.
Oh comments under pen names and even personal insults under such cover go back to before the founding of the US and all the Federal Papers for example was written in this manner.
Hamilton and Jefferson and their supporters traded insults and charges under the cover of pen names.
If doing so was good enough for the founding fathers it is more then good enough for this website.
