It almost seems to me like everyone is of the same old mentality that building a few thousand links will skyrocket you to the top and that spam is the answer.
First I want to say that even most professional blackhat SEO's don't spam links anymore, or at least not blog comment and forum spam.
If you are going to do blackhat SEO I would suggest sticking with web 2.0 blog networks and pbn networks, remember though, you always run a risk.
Instead of spending money on spam links why not create some good content and then share it to communities? Email other site owners and let them know, this is the real way to start ranking .
I just wanted to write this post because I see this same old weird mentality that spam will rank, I just hope this points someone in the right direction.
I did write a blog about the same thing: 11 SEO Tactics That Could Destroy Your Website | (Note: I wrote the article but I don't own the website at all)
What do you guys think? I think the number one problem around here is some weird kind of cling to outdated information.
