Does this look ok to you? GWT Question
 

Why the hell have my blocked by robots.txt pages shot up since the beginning of August?

No idea if this is also behind the reason traffic has been falling.

This is my robots.txt file

[CODEUser-agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: *?replytocom][/CODE]

not sure if I'm understanding your question correctly, but blocked by robots pages are now indexed, with the snippet 'a description of this page is not available because of this sites robot.txt' or smth similar.

Go to parameters and disable urls with replytocom. Solved. Bye.
