FAQ
What is this place?
4chan will periodically (every 15-60 minutes) publish a small list of bans that have been handed out on the website for transparency. This website exists to archive those bans and uphold that transparency.
What happened to 4bans?
4bans is still around. I'm not affiliated with them. Their DNS provider was having "major issues" - I don't know the full situation. They are still accessible through their IP address directly: http://185.10.68.107:1776
And if you're the 4bans guy and you're reading this, keep up the good work.
