Yes I have seen some spammers are doing this as well.
I hope so as long as that update is for good and quality sites don't get hit. Hubpages did the same thing brought all of their content on subdomain and bang they were ranking for tons of keywords so in a sense it is working at sub-domain level as well. I seriously HOPE Google will fix this.
We never recovered fully to that 100% level. We tried everything and it got worst and worst. This is for one of our website where we are the real brand and the rest are our affiliates or MFA sites.
We have tried tons and tons of layout with different design, content, images, videos, etc etc but no luck never recovered 100%.
I was not talking about .in but I guess it is worst in Google India.
I was never so active on this forum before Panda. This update has messed up REAL GOOD SITES that is the sad part. I still have sites in top position.
The reason most of us are going through hard time is that the current top#3 are nowhere near our content nor deserve the position. They break all the rules/regulations and still they are ranking.
It looks like best alternative just start all over and your overall investment and time will be much less than if you were to work on your site that got hit by Panda. What really killed me was that my "widget" site which I can show to anyone and they would agree it is better than top 40 results. I am now on page 5th.
Just because I don't do some stupid social stuff? But I feel nobody wants to talk about my niche in social sphere unless I hire people to do fake tweets and likes.
Niches that we track, it seems that smart ones are taking those measures you have mentioned however it is not necessary.
I see same hosting, same domain whois, same GWT, same Adsense account, same design, same theme, same content, same stolen images, and so on. Just FRUSTRATING.
