Thanks so much Olivier, this should help a lot.  Just an observation.  If you get two karma points for posting a new question and lose two karma points for a down vote, then you are at zero or (say twenty) and can continue to post spam.  Maybe a down vote should be worth -3 karma points.

The situation has indeed gotten much worse these last days, so here are the 
things we have done to limit the spam level at this point:

- Mass-delete the spam posts and the corresponding users via an automated 
procedure. Probably did not catch 100% but a good share of the spam.

- Fixed the karma system so karma levels are checked also when posting new 
questions, answers and comments (previously if was not checked so users with 
negative karma were still able to post). This will enable users and moderators 
to permanently block a spammer by lowering him to a negative karma.

- Changed the karma levels:
   + a karma of 20 is now required to be able to post or answer a question (yes 
obviously this is a problem for new users, we will lower this later - see below)
   + removed the karma bonus given by posting questions/answers (you should 
only get bonus if someone else upvotes your posts)

- Work-in-progress: we are adding an optional email validation step on the 
forum - if you just signed up and have 0 karma you would get a notice on the 
forum index: you can validate your email and get some karma - just enough to be 
able to post your first question.

We hope to finish the deployment and fix the karma levels accordingly in the 
coming days.
