Google Doorway Penatly

[Zubairjani]

Ok so i have been trying to figure this out for about a month now.
The case: I have a blog network with unique content on each post and at the end of each post each blog links to x1.com/unique-url-for-each-post before linking to x1 in the post i use a redirect with like this: theblog.com -> redirect-url.com/redirect.php?=x1.com/unique-url-for-each-post -> x1.com/unique-url-for-each-post
(all links at the bottom of the posts have no-follow)
For some strange reason about a month ago all blogs which i have done this on lost around 90% of their traffic.
Could this be the cause of the penalty? Is this type of linking considered as link farms by google?
All help and tips are greatly appreciated!

Definitely, it gives a definite reason to implement restriction or put penalty on it.
