Code to prevent linking from specific site(s)
I know this is possible because I have seen it done on a commercial site.
What I need is code to prevent somebody from linking to my board (any where on my board) from a given site. If somebody clicks on a link to my board from that site, they should get a custom error message that says something along the lines of "We do not welcome traffic from this site" or whatever.
Every once in a while, I get "freebied" by some of the major freebie boards. They descend and kill my server and I would like to shoo them off.
