LinkEX

Hello,

My link exchange partners have trouble when adding their links to my site, because I setup my LinkEx script require min
PR 1, below is some of the domains list that has different page rank result:

frogsoda.co*
PR check result by LinkEx = 0
PR check result prchecker.inf* = 4
justgamelinks.co*
PR check result by LinkEx = 0
PR check result prchecker.inf* = 1
your-arcade.co*
PR check result by LinkEx = 0
PR check result prchecker.inf* = 2
ultima-arcade.co*
PR check result by LinkEx = 0
PR check result prchecker.inf* = 2

For your information, below is the domains/ips I posted to the Google data data center field on the link verification
settings:
