The suggestion goes first (I already suggested it in some spammy thread in T&T):
What about adding a [show T&T] and [hide T&T] button on the stats page e.g. in the (Today's) Top Posters section ?
Then we could see if the member was in a spammy mood today 

 and helpful members who don't post much but useful posts could get a chance to be in the Top Poster's page instead of some semi-helpful spammers 

And people who just want to up their postcount can reconsider their (spammy) behaviour when they see that most of their posts are spam. (e.g. John 

)
And now the question:
As some people mentioned, the registrations go up but it seems that posts get rarer. I myself think that, when I joined, there were a lot more posts (partly because of Sean 

). Maybe WDZ could make some stats like the total monthly postcount for the last half year.
Now, this isn't so serious even IF the total postcount got lesser, the forums won't die 
Neways, hope you all are having a happy pre-christmas time 

 (btw, it's snowy in Berlin 

)
Edit: Just spotted a typo in the title 
 took me 18 hours to notice...
