Several times over the years we (Simon, Peter and Simon, the editors of TA) have posted reminders encouraging “good commenting”. One of the common themes is the number of pseudonymous and anonymous comments. As long ago as 2009 we wrote:
please consider seriously using your own name, rather than a pseudonym. While we do not, at this time, intend to make this a requirement, we do wish to strongly encourage the use of real names.
This request still stands but we have also decided that even where we allow pseudonymous comments the pseudonyms must be distinct. In particular we will not publish comments that come with the tag “Anon” or similar.
Long-term pseudonymous commenters may wish from time to time to sign comments with their real names, even while continuing the use of the familiar pseudonym.
