I see your point, and had considered that aspect of it before i deleted the link. However, other factors entered into my decision. One is that well known and safe links are one thing, but some others i'm not comfortable leaving on open forum.
There had already been an instance of someone essentially drumming up business for themselves, which makes the "help" factor questionable to my mind and i think thats vastly diff from sending someone to bn.com.
note that i do not mean to imply any dishonorable intentions by, or any offense to, the poster of the url i deleted
