Here is what they are saying over at federalreviews.com about the Linkvana service:

“The search engines have gotten very good at identifying links coming from so-called ?bad neighborhoods? like link-farms and the like. Internet marketers have found it very difficult to generate a significant number of quality links without spending months working on article marketing and Squidoo lenses.

Currently, the best options for getting quality links are directory submissions and buying text links from sites with high page rank. This method has proven to be very expensive and difficult to maintain. That?s where the Linkvana service comes in. Linkvana went live in late 2007 and decided to only accept 300 members. The creators had to limit the number of members in order to preserve the integrity of the program and the back-links being generated.
The way that Linkvana works is by allowing members to create blog posts that are posted on high-quality blogs with Page ranks of 2 and up. Each post can contain one link to any page of your choosing, and the member can even control the exact anchor text of the link. This is a very important and valuable feature, as it allows members to focus on optimal keywords in order to maximize traffic from the search engines. Linkvana allows members an unlimited number of posts and domains, but it does limit the number of posts per domain to around 5 per day. This is actually a very useful limit because it allows your links to build gradually and in a more natural manner.

Linkvana is by far the best link-building service that I?ve used, but there are a few drawbacks. One is that this is more of a do-it-yourself service. Each blog posting must be completely original and needs to be at least 100 words in length. For those of you that hate writing or are unable to create enough original posts, Linkvana will create original posts for you for only $2 each. You just have to tell them where to link to and what anchor text to use?their expert writers handle the rest.
Unfortunately, Linkvana has one other major disadvantage, its cost. The service has a very steep price tag of $147 per month. This makes the service not affordable for many marketers, but the high price helps to maintain the quality of the service by keeping the number of members lower.

Linkvana is not a good choice for those just starting off in online marketing, but it provides a very valuable service to more experienced marketers that are looking for ways to increase traffic. This is truly an excellent service and would have received a higher rating if it weren?t for the high price tag. Linkvana does what it was designed to do, just be sure you are capable of taking advantage of this powerful tool before laying out the money for your membership.”

LinkVana‘s main goal is to provide quality links to all of its members. Remember our motto – “Quality above all”. And because our job is to protect the quality and integrity of our network of sites, there are a few restrictions when using our service.

#3 – LinkVana will not be used for link spam.

Any violation of these restrictions will first result in a warning to the offending member, and all violating posts will be removed. The second offense and the member will be terminated from LinkVana. These stipulations should not be viewed as negatives. We want to keep our network free of anything that could be viewed as a negative by search engines, which is a great benefit to you.
