SEO problem: Duplicate content in tags pages (vB3 BUG)

It seems that tag pages lack of a check for navigation like forumdisplay and showthread pages have. This generates a lot of duplicate content which could penalize forums in Google and other search engines:

For example check this page for london tag, as you can see the latest page is 10.

However if you manually edit the number you can generate lot of other pages which will have the same content as page 10:

I have seen Google indexing tons of pages with the same content like this.

It seems that vB4 have fixed this issue, because i can't replicate this, instead i get a
"Sorry - no matches. Please try some different terms", but i couldn't find a way to port this.

I have been thinking on creating a <link rel="canonical"> tag for these pages however i'm not sure how i can handle this with hooks in tag pages.

Any help will be greatly appreciated.

I use robots.txt to block tags from being crawled. I do not believe them to be seo friendly any more. I don't think any list of keywords is any good any more at least for Google seo.

I believe the tags system was mainly designed for use inside the site, not seo.

Lastly, I know you catch this stuff on GWT but I really think Google's current algo is smart enough to know the difference with this type of duplicate content. I doubt you would be "penalized" for it.

Let us take care of your forum, seo, seo reports, maintenance, what ever you need.
