Hostgator's paid backlinking program by Attracta - advisable?

Do you have a link to the plans they are offering? I could take a look and give you my opinion. If it's legitimate guest posts (find niche blogs, offer to write for them, get an article published with a link back to your site), then there is really no downside to this and yes, it's completely safe. There's no way an algorithm update could target legitimate outreach like that, as long as the blogs aren't apart of any network that can be traced. If they are all individually ran and there are no footprints, I'd say you're good to go.

Your first doesn't work without a user account.

I was sent the timeline of progression first and then the Gold package info (July 19, 2013). After going over both documents, I agreed to enter into a contract with Attracta to get our business to the top of Google. I should have had my onsite content by Aug 9, according to the timeline they sent me. Instead I kept getting repeat emails of the Knowledge Packet over and over again. It was not until Sept 11 that I received the onsite content – a whole month late that I had to pay for. During this time, I also requested the additional service they offer for $300 to install the onsite content for me, as laid out in the original agreement. They ignored my emails and I was unable to receive this service. I had also asked some questions about editing my website. Those, too, went ignored. When they finally did send the onsite content, I was given two weeks to install it or the contract would be null and void. Because I was unable to get the additional service, I was unable to fulfill this part of the contract. Attracta had only ignored me and sent me repeat emails. I decided to cancel. Even after we agreed on a refund amount, Attracta gave me the runaround for months. This is the tame version of what they’ve put me through.
They offer a 60-Day-Guarantee or the customer gets their money back. They were unable to get us to the top of Google in 60 days because they couldn’t even get the onsite content done on time. They couldn’t even answer simple questions in emails. They couldn’t call me when they said they would. I spent days waiting on replies that never came. Even though they could not do their job, I never received any money back.
Attracta breached their contract 3 TIMES and completed no services for me. I paid them $2894, and I have not seen a dime returned. What little initial work they did was very low quality with misinformation and misspelling. I turned them into the Better Business Bureau, and they would not cooperate with them either. They have since had their accreditation with the BBB taken away due to the number of complaints they’ve had. I even tried to contact the co-founder, Ken Leonard, to which I still went ignored.
If you are a victim of the Attracta scam, here’s a few things you can do:
Google “Attracta Reviews” and leave your two-cents on every page you see so that others may be warned. Go to Internet Crime Complaint Center (IC3) | Home and report the business fraud/cyber scam to the IC3 division of the FBI. This is more time consuming but worth it! I’m working on my case there now. Report them to the Better Business Bureau. Part of my decision to hire them was because they were accredited on the BBB. Help future potential customers to know the truth by reporting your experience. Suing is certainly an option, but if you’re like me, you’re out of state and things get more expensive than they’re worth. That’s why I will spread the truth of what they did to me online. Also, I made an Angie’s List page for them. Feel free to leave a review there as well!
