I've checked my link trades today and had to take down links to the following sites because the owners didn't honor our agreements and have taken my links down.
http://www.michellebxxx.com/links.html
http://www.madatit.com/links.html
http://www.24webcamsex.com/
http://www.realpunting.com/links/
All those trading links with the above sites, you may want to check your trades as well.
