Last week, a "419", or "Nigerian Wealth Scam" post was made to
the Group. I was unable to remove the poster's privileges; by
the time the post was found, the poster had left the Group.
I did not wish to make this a Moderated Group; it might interfere
with its ability to be syndicated. But in view of this new
problem (scammers joining to make a single post then leaving),
I might consider it.
Any thoughts the members might have on whether full moderation
would be needed are welcome.
