Page links that do not error and many different home pages indexed by SE

[jpietrowiak]

Here are some examples that I see in the search results for site:site.com in MSN. There seems to be an excessive of them all pointing to the home page. Any idea what the extensions description is for?

I also noticed that site.com/? (place anything here) does not ever return an error page just goes to the home page of site.com. ?

site.com/?id=877&​action=new
site.com/?id=30
site.com/?id=831&​action=new
site.comid=741&​action=new


Thanks

OK I figured out what the /?id links are comming from. I put a redirect in htaccess from my old forum that was located at site.com/forum/?id for example

here is my redirect in htaccess
redirectMatch 301 /forum/ http://sub.site.com/

Should this be something else I am trying to divert the traffic from old Punbb forum to new vbulletin subforum main page.
