vodlockertv.com
biggboss.org
infoocode.com
newyorkpersonalinjuryattorneyblog.com
moringajuice.wordpress.com
surrogacymumbai.com
maximizedlivingdrlabrecque.com
radio.com
gossipcare.com
tecteem.comI haven't dug into the logs, but most probably we saw that https://news.ycombinator.com/submitted?id=thebottomline was spamming HN and banned the sites that they were spamming.
Edit: if you (i.e. anyone) click on those links and don't see anything, it's because we killed the posts. You can turn on 'showdead' in your profile to see killed posts. (This is in the FAQ: https://news.ycombinator.com/newsfaq.html.) Just please don't forget that you turned it on, because it's basically signing up to see the worst that the internet has to offer, and sometimes people forget that they turned it on and then email us complaining about what they see on HN.
