Dude don't scare people away from accepting someone's great offer. If you are scared of backlinks why are you on a blackhat website?
I am the creator of NHSEO and in every case where anyone has claimed that NHSEO has negatively impacted their website I have extended an offer to look into it personally so that I can offer advice on a way out of it or to explain exactly why the website was negatively affected.
Guess what, I have yet to see a single instance where NHSEO was the cause of penalisation. All cases have been due to questionable content or on-site details or simply the website was not indexed yet.
I don't wanna get on your case about your comments too much but you are wrong and you are giving out bad advice for people to not use a service that someone is giving away for free to people that maybe cannot afford their own software right now or are just learning the business.
I am not scared at all from backlinks...I like backlinks but carrefuly made ! And after all I just said my opinion..is not like I killed someone .
