I have a lot of sites on different subjects ranging from video games to computers (but no gambling/adult websites). When searching thru different forums and website about people selling links , i noticed people do not like to buy links on websites with links to gambling/adult websites.

Does this lower your ranking? Is there a problem if you do this? Why do people not want to buy links on websites that do this?

The reason i am asking is i am selling links on one of my sites. I would never sell any links to adult (sex, etc) websites but i don't see the problem in selling links to gambling websites?

Please enlighten me.
