When setting up the board I forgot the most important part: the spam filter. After four days of not having a visit to the site I was welcomed by 64000 (sixtyfourthousand) new messages of spam (without a can).
Seems the domain is targeted by a botnetwork of spammers or something and I need some time to figure out how to resolve it.
Will post an announcement when its done. Thanks for the interest @Dan Allen
