I dont think you are getting it. I searched EVERY link out of the 300 they gave me. And guess what? 0 backlinks.
Don't tell me to check Yahoo Site Explorer. I checked the source code. Not only is MY link not listed, there are NO backlinks on any of these websites that are added by anyone except the owners of the sites.
It is a straight up scam. Not false positives. It is a lie. I am not a competitor with them, because I actually offer a service that delivers. They offer nothing. Check their own website in Yahoo Site Explorer.
"We have calculated our stick rate to be somewhere in the vicinity of 5-15%. Your mileage may vary. Links created towards educational, information websites generally receive a much higher stick rate than links to hardcore adult related websites for example."
So, for the "50 backlinks / day" that they advertise free, they only EXPECT 5 of them to stick on average, but they wouldn't be surprised if NONE of them "stick". What a rediculous, worthless service.
Why would they advertise a number that they only expect to be able to deliver 1/10th of, and if my case, 0/300! What a great way to spread the word of your fantastic service by offering a free trial of NOTHING.
