googlebot ignoring robots.txt

Some excellent suggestions, thanks. But most are over my head. I ended up replacing the individual post link with the permalink, and dropping showpost.php from my sightmap (duh!).

The problem was that I just upgraded to vb3.6.5 from vb3, and it handles showpost very differently. Instead of keeping the post in context, it shows just the post. And those were getting better ranking than the threads themselves on google (and with no ads).

vB 3.0.x and 3.6.5 handle showpost the same way. Both showed just the post.

With vBSEO, using the Permalink option, it converts them show the whole thread, and jump to the anchor tag on the appropriate post.
