I regularly get emails from people asking to buy text links at http://www.ScamFreeZone.com .
Why?
Perhaps because it’s been around since 1997. Perhaps because it was once PR7 (for a short time). Perhaps because it ranked very highly for “home business”, “home business opportunities” and even “business opportunities” in the past. It probably still ranks highly for less competitive phrases. Perhaps because I have very few links on the page, so each link carries quite a bit of PageRank.
I don’t know.
Nor do I care.
I’m not selling links.
Go and build your own PageRank. 
Why you should not sell txt link from your site?
“Selling links muddies the quality of link-based reputation and makes it harder for many search engines (not just Google) to return relevant results. …”
