Two things.
First, I have played WoW and I am very familiar with that site. I am actually very familiar with most of the levelling guides and what not on the internet, since I played WoW for a little over a year.
Second, if you disagree with it, you are more than welcome to PM Kaol, since it was by his suggestion, being here longer than myself, that it was removed. Or any other admin for that matter. If they feel it's appropriate and want to allow it, then I don't have an issue with it. But if I am told that we remove the links then I remove the link. It's just that simple.
And, at the bottom of the pages on that site are gold selling ads and wow cheat ads that link to things that are against the blizzard TOS, I did check it since I need to explain my actions it seems.
