IF all you have as links is spammy comments and no other links (articles,forum profiles,directory listing ) then with all the complaint from pissed off blog owners, you might get sandboxed.
Diversify your links. if you have articles links, profiles links, bookmarking links, directory links then uncle GOOGLE will look kindly at any complaints from blog owners as it might be the work of competitors.
But if you just have comment links with many repetitions of the same words, over and over again, you might be suprised at what will happen to your site.
Scrapebox is a "NUCLEAR BOMB" for getting links, but that does not mean you start shotting at anything that moves.
Direct some of your fire at sites you have approved comments on, give them comment links.
Create blogs at the free blog sites like:
wordpress
blogger
squidoo
tripod
etc etc etc
then diect your fire at them. They move up, your site will move up.
Google is getting tens of thousands of complaints from webmasters everyday and it is just a question of time before the fools ruin it for the wise.
If all you want is to rise up quickly in the Serps with no regard for longevity, then please, blast away.
But if you need to create long term income, then use common sense and build your online real estate with care and on solid ground. Think before you start shotting, create many, many different links to withstand scrutiny.
From life experience, the easy road turns out to be the hardest after all.
Let us make this last! I HOPE!
