Spam destroying DAFNE forum

Something needs to be done about this spamming. I have written a letter to the head office at DAFNE for further resources yet did not get a response. The forum site and its managers are doing a great job but clearly require assistance as it has become like a sieve for anyone to sell crap. This continuous spamming of our great forum is destroying the validity of our site and as stated before we have extremely vulnerable Type1 diabetics using the forum.
