And what happens when a new person begins an off-topic thread? Wait
some period of time until the regular message pops up again?
Yes, why not? I think anyone posting to news knows that they have
to monitor the groups for a few days afterwards to receive any
replies. If that reply comes a few days later covered by the
'catch-all' off-topic reminder then what of it. They have been
told why the message is off topic and wis not best dealt with here.
Of course, if that isn't good enough, the net police can always
email the user and point out to him that the articel is off-topic
- they could even use the same text as the standard recurring post.
That at least would not distract everyone else reading the group.
Even better, since the various memebers of the police can't see
each other's emails the user gets told the same point over and over
to drive the point home.
No mechanism is going to be 100% perfect - the aim should surely
be to minimise disruption rather than complaining that such solutions
are not 100% effective so we shouldn't even bother. The status
quo is hardly a better solution. There isn't really _anything_
you can do about people who do not refer to charters or at least
a few previous messages before posting short of moderation, which
I don't think is particuarly justified here.
