I have a huge list of drop places but I'm wondering if there are places you should not put your link. People talk about "bad neighborhoods" but what exactly is a bad neighborhood and how do you know if the site is included? Are there subjects (for blog and forum links) that you should avoid (sex, drugs, etc.). Some I wouldn't link on just because of my personal beliefs but I"m wondering if there are any specific subject matters that should be avoided. Thanks!
