LinkEX

A cordial greeting to all.
I must start that I am using some of my sites in the script LINKEX.
Some webmasters say that among the many things not approved by google, one of those are automatic exchange links
scripts, and also argue that the string generated <!-- Output generated by LinkEX (+http://linkex.dk/) --> that
identifies clearly that the exchange is run by linkex and it is generally manual.
This is a problem for the black hat seo?

I've got the same problem, I created a page within all links from the LinkEx-script, but I think Google just ignore the
page, so it will never be crawled by the GoogleBot.

I also discoverd that directories who are using the "php Link Directory"-script can't find your backlink if
your link is on same page within the LinkEx-links or if the link is added with the LinkEx-script.

If you delete the generated string "<!-- Output generated by LinkEX (+http://linkex.dk/) -->", it will
not solve the problem!
