The situation is improved on what it was, but still unacceptable.  I have Moderator privileges
on the Forum and in 3.5 hours I have banned at least 15 spammers and directly deleted their
postings/topics rather than move them to holding locations, as I see no need to clutter these
up with undoubted spam; there have been sometimes as many as five or six postings by a spammer.
Acknak and Hagar have also been active during that period and I do not include their totals;
the moderator logs which are accessible to Apache Observers will show the extent of the problem,
which a visit to the main pages of the Forum will not, as we are trying to keep the Forum
running as normally as possible.
