I haven't been to board77.com in ages, but b77.com gave me porn, yeah.
As for the travel ads and stuff, it is my uneducated opinion that that is what happens to websites no longer being paid for. I read a lot of movie reviews which are linked to from the IMDB and with many of them, it'll say the page is no longer available but give you some advertisements to check out instead. There is probably a reason why some sites do that instead of giving you "404 Forbidden" or whatever, but that's what I think.
