The text link exchange network Link-vault that I wrote about almost a year ago introduced some changes that I find pretty unique and notable today:

Single link placement : while the usual setup of link-vault displays it's links like usual footer links (up to 5 links besides each other) there's a new hack out that allows you to spread the links all over the page – i.e. place 2 in the content area, 2 in the navigation area and another one in the footer… that makes the text link vanish even more in the site's content, hence giving it more strength and making it harder to detect

Global Domain banning : while webmasters had a hard time to ban domains they found not legible for linking, Sensei of link-vault now introduced an easy "Global domain ban" for getting rid of bad content sites, scammers that try to redirect legit traffic and generally questionable content sites that made it thru the strict review process somehow

These features set link-vault apart from other link networks out there again… I'm very keen to see new features coming up there…
