I moderate a Google Groups which gets a lot of spam.
Messages from newcomers must be moderated before they get posted.
Usually I select and allow the valid messages, then select all of the others and ban them altogether.
Problem: Sometimes I get this message:
Error while banning members. One or more members were not banned.
Refreshing does not resolve the problem. Actually some moderators have learned to live with a broken moderation queue for months.
How to empty my moderation queue when that happens?
