Spam comment deletion

On the first day of the month, any comments that have been marked as spam will be deleted. Please note this does not affect comments which are awaiting moderation.

For further information on how to prevent and handle spam comments, see: https://blogs.ilrt.org/2017/05/23/handling-spam-comments/
NB: Due to changes in how Akismet works various sites that have Comments enabled do not have spam protection properly configured.
