Yeah I too am a victim of the -50 -60 google penalty and has been about a month and 10 days since the penalty was applied to my site. I feel as though I have corrected everything that it could have possibly been, guess I just need to wait 2-3 months as most of these penalties seem to last! I wish I was as luck as you ERIND and received an email from google stating my reason for being penalized and how long it would be!
