How good is Drip Feed Links? (Internet Marketers)?

[Marshall Adler]

There's a website called: http://www.dripfeedlinks.co/

These guys offer to build daily back links to various websites for you by
submitting a percentage of blog comments and forum comments with
links to your pages using various keywords you instruct them to use.

I've been holding off on paying for this service because I can't find
any reviews online from real users about this site.

I really need to know if this site is good. Can anyone tell me the truth?

Do the links from Drip Feed Links really push your rankings up?

What kind of Page Rank do the blogs and forums have that these
guys post links on?

Thank you for giving me an honest answer! NO SPAM PLEASE!
