Can comment spam on those high pr sites caused the whole website ranking dropped?

[suyvv]

Hi there, I really need some help here. My website is 6 weeks old, the main keyword I'm promoting was at around position 45 a week ago, other 3 buyer keywords that were ranged from about position 8-20 without too much of linkbuilding, I also had a low search volume low competition keyword at No.1 without any linkbuilding work before.

I started comment spam a week ago, I comment on those pages that contain many spammer links, most of them had OBLs less than 100, yet some of them have more than a few hundred or even 1000+ OBLs. I put 5 links that each links to 5 pages of my website, with identical anchor text and comment words on each of these sites earlier, later then I decided to use spun article as comments. So far I've built about 20+ pr3-pr7 backlinks over the week, most of them are pr4.

I found that my main keyword's position started to drop a few days ago, yesterday those buyer keywords' ranking had all dropped, now they are in position 30-60, yesterday my main keyword was at 49, now is at 235! I also found the ranking of some other keywords that I hasn't promoted has dropped. The keyword that were at no.1 before is now at No.10.

So does this mean google has detected my spammy activity and penalized my website? Or is it because many high pr backlinks charged in could cause the ranking become unstable for a while(just my thought..)?
If I don't build backlinks to them anymore from now, would they regain their position by themselves?
If I could remove those spam links I posted before, would they get back to their original positions?
If I keep update contents of my website like Vita did in the video using the DDET tag, would it help? If so, should I update all of the pages as all of their ranking seem to have dropped.

Any info will be very appreciated. Thanks.

IMHO you should refresh your pages with new content and diversify your link building activity.
Get NOFOLLOW links.

It's suspect if your young site gets a lot of high PR links quickly
AND those links come from pages heavily spammed
AND you only get DOFOLLOW links...

This kind of link building wouldn't have any negative impact I think on an established website but on a brand new website that might raise a red flag.

I have heard that it does not affect your site as then your rivals could spam you off the first page.
To be safe, I think VV's advice is still the safest and has long term advantages.

Thanks for the reply Vita, I'll gonna follow your advices, hope my site will return to its original position soon.

Hi Eddie, I've heard of that as well, but I believe google's algorithms are improving and they may have already know how to distinguish between spamming it yourself or spammed by others.
