How to recover my inclusion in google results after being penalized for receiving comment spam?
I put an update of my site live and I forgot to enable to comment approval queue. I noticed a few days later I was linking to Russian porn and my Google rankings dropped by about half.
I have removed all of the links but I still have low rankings, Google has not crawled my spammed pages yet.
Is there any way I can speed up the process and how long will these links tarnish my ranking?
