I put a bandaid on it.
I used [unknown]'s mod and changed the / to _ and opened up the message index pages to show 200 threads per page.
That should get them all spidered then I will close the indexes back up to 20 per page. (not customer friendly but it gets the job done)
site:yoursite.com
yoursite.com will give you a list of all pages currently in the google index. As best I can tell google has not spidered any pages from
yabbse.org that contain the XXX/XX. Only the XXX portion
My guess it that it looks at the / past the ? as being a control character, that is my reason for trying the _ instead.
