Yes saying this because site which was making me $5000 per month got deindexed using such links, right after i used sape links, i got penalized in a week.
Do not use SAPE. These links will steal your money, ban your website and sleep with your
girlfriend while you are at work. Dirty high PR bastards.
In my undestanding Sape are short-term links, but you can probably rank for competitive terms like viagra if you know what are you dong. The ranking will probably last for few months but who cares. That is quite enough.
Why would anyone build tiered links to one month wonders? This sounds like one of the most ineffective strategies I've ever seen. lol
