Okay so I downloaded a free theme off the net and the Footer of the webpage had a hidden link in a cloaked color! I don't want my site to get banned for cloaking..... When I looked at the php file it is encoded and I cant decode it to remove the footer spam! I have uploaded the code below because it's to many characters to paste here.
It is illegal to remove such links without the permission of author - talk to him or forget about it.
Themes use the code released by Wordpress under the GPL, which means you never have to retain the links in the footer! Second of all if you look at the code it maliciously put there as its a hidden link that blends in with the background color and also why would you encrypt it that much unless you were hiding something??
Most encryptions like that mainly use base64 and eval. Just use base64_decode on the really long string.
I tried it, it works. It is easy, I won't give you the answer, this is not what this forum is for. I have told you how to do it.
