Checking my link trades for my webmaster resource/traffic trades site and I found a LOT of dead links, some for example:
(edit, dont mind these link titles, i actually hate this new vbulletin feature)
free porn gamma radiation monitor at ipron.net
dating advice chat online now at adult-traffic-trade-sites.com
http://www.kt4l.com/trade.php
http://schoolthumbs.com/sites.php
just to name a few, there are actually LOTS more, just fyi for you in case you want to remove those dead links
