Although forum.dlang.org has had a spam check and used reCAPTCHA since it was announced, it is only somewhat effective against fully-automated bots - it is powerless against humans paid to post spamverts on forums web-wide, which is what the current spam economy seems to be gravitating towards.
Coincidence? :)
