There is an unregistered user, Alphonse, who continually answers questions with long blocks of text. While a part of the answer may be helpful, the bulk of it is a long rant in something of an essay form:
"Photons have momentum because that is the way our Universe works."
I've edited some of his answers hoping he would get the hint, but I think that since he's unregistered perhaps he's not able to see that his posts have substantial edits.
I've since stopped editing his answers but was wondering if there was a better protocol for handling this.
