Lemme go back and research some multiposts that I (and others) have
manually flagged and see how effective a keyword search would be. I

But my point is that the messages aren't cancelled... at least not on
my newsserver. Are they cancelled on yours (ie, do you see the reply

I was talking about automated spam cancels (by filtering systems), not
user cancels. Or is spam filtering done prior to publishing the post?
I'm not sure how newsservers filter out spam.
> If he has [replies], then don't post (IIRC you do that now?)
Not quite. The bot will flag the original multipost, even if it has
replies (it ignores ALL replies, including replies which might be
cut-and-paste answers to multiposted questions, or even cut-and-paste
answers to similar questions, either of which would hash out as
multiposts but aren't really multiposts, IMHO).
But I'm not sure that it is undesirable for the bot to reply to an
answered thread. There have been past cases where I've (unknowingly)
replied to a multiposted question, only to jump to another group and
realize it was multiposted. In that case, I still respond back to both
threads and flag the post. Even though I previously replied (and, who
knows, I might have even replied correctly), flagging the message may
discourage further "rewarding" the OP with additional assistance (or
corrections to a crap answer I gave... serves the guy right).
I'm not sure why the bot should not act in the same manner...

Yes.
Notice that a cancel message is a post with a request of removal. Each
news server can be configured to honor such a request, to not honor it
and can be configured to propagate such requests or not.

IIRC a spam filter will just drop the post. However, there are cancel
bots that work similar like yours, they just post a different message
(cancel), and there is a delay with those, of course.
I am also talking about manual cancels. In general you don't want to
reply to *any* message that is canceled. Practically this is impossible,
so I would be happy if all spam is not considered multipost.

IMO no. Just assume that if there has been one reply that the poster
just got away with it. You might catch him/her later anyway. I would
(again) recommend to limit the number of messages the bot sends out.

This was quick and easy, and I have done so.
I also noticed earlier that a pyramid scheme got flagged. All pyramid
schemes will contain an e-mail address in the message body (but real
multiposts rarely will), so I have coded around e-mail addresses as
well. Presently, messages are ignored if the message body (excluding
cut/tag line) matches per (using Regexp::Common):
if ($body =~m{
$RE{URI}{HTTP}{-scheme => qr{https?}}
| $RE{URI}{FTP}
| $RE{URI}{news}
| $RE{URI}{NNTP}
}xms) {
$log->debug("Ignoring msg with URI (spam?)");
next MSGNUM;
}
if ($body =~ m{($RE{Email}{Address})}xms) {
$log->debug("Ignoring msg with e-mail address (pyramid?)");
next MSGNUM;
}
I think that will ignore 99% of spam (with very few false negatives).

Yup, you can't ignore them based on a simple count of $$$$$ :-D.

Something you could perhaps try is keeping a database of all your bot's
posts and cancelling them if the original article gets cancelled.

Not sure how to do that... can I query for canceled jobs? Or would I
need to just check every post and see if it was still available?
Of course, in this particular case, apparently a message was canceled
on John's newsserver but not on mine (GigaNews). The bot runs on
GigaNews; it has no way to know about cancels on other servers.
I have never heard anything negative about GigaNews (such as that they
don't honor cancels). One thing I can say for sure about GN - it's
darn fast. But, if I find that they routinely don't honor cancels that
other servers do, I'll regroup.

I admit I don't really know, but I would have thought that the control
message would just come down to you with the rest of the news. Then you
can grab the msgid and cancel your replies.

Hi All,
Just a quick question...
Is there a regular expression that I could use that would fail if a
number has a white space(s)embedded in it?
For example:
1.5 <-- Should pass as a valid number
1 .5 <-- Should fail since there is a white space in between the 1
and decimal.
Any help would be greatly appreciated!
Thanks,

Well, that is not a number.

You understand that each of the following would pass this test, right?
"5."

OK, I'm offically freaked out. That is exactly what happened this weekend
when me and my wife went to see "The Decent" at a movie theatre.
Only in America.

No. I use perldoc -m (in its current incarnation) all the time. perldoc
-M is taken as well.

Another one is "sort".

Really?? That doesn't even compile.
my $SQL = q {
Select Result,count(*)
from DataListing
where InputDate = "2006-07-14 13:44:13"
group by Result
having count(*) > 1
};
You'd be much better off using placeholders. e.g.
my $date = '2006-07-14 13:44:13';
my $SQL = q {
Select Result,count(*)
from DataListing
where InputDate = ?
group by Result
having count(*) > 1
};
my $sth = $dbh->prepare( $SQL );
$sth->execute( $date );
