Right, but it is by some, which I learned the hard way, so to maximize your acceptence I'd rather sacrifice one ad link to make sure I was kosher with all LL owners. Right now my LL is just starting up so I'm not too picky either way ;)

And personally I liked having links back to my hub when I was building, it let me control the traffic. Others think it's a waste because if the user is going to be clicking on something, might as well be something you might get paid for.
