Answer 1

Hi zeeshan,

Same thing happened to my website.

any solution?

Answer 2

I had the same problem.  A very simple solution is to add these in the robots.txt:

Disallow: /user*
Disallow: /register*
Disallow: /login*
Disallow: /ask*
Disallow: /forgot*
Disallow: /chat*
Disallow: /admin*
Disallow: /activity*
Disallow: /questions*

EDIT:  I just changed the above rules to make it more efficient.

After you fix your robots.txt, you can test if it really blocks the desired urls from WebMasterTools:

Even better, go to the new Google Search Console:
ttps://search.google.com/search-console
