I tried about 4-5 IBL tools. Amongst them are Mcdar and Dot Seo All of them are showing 0 or -1 at IBL's for any website, on any DC. SOmething is definitely happening. Is google changing the interogation scheme ? Or, are all these websites banned ? So they can not ask info's from google ? Awaiting your stuff
-1 for me as well with IBL -1 for indexed pages backlinks show up just fine from other search engines on dot seo (by the way, never seent that tool before, thanks for the additional resource)
Go do the link checks manually. It's just those tools having a problem for some reason. I have a custom page I wrote for myself to keep track of my own sites and that page is working just fine.
