As a temporary measure, I've had to close the DCF forum which used the punBB code. It was continuously attacked by hundreds of bots every minute, to the point where it slowed down the whole server, even though nearly all spam was blocked.
Unfortunately SMF seems to suffer from the same fate (the forum was invaded by bots only minutes after I installed SMF). If you have better ideas, you can email me to fwi at inducks.org.
No DCF discussion is lost and I promise everything will be restored at some point.
