Nothing much you can do on a forum except ignore it and post as many SPAM badges before the Admins get to it. Never click on the hyperlinks which are posted. These can possibly cause mayhem on your system.
There are SPAM monitoring services which forums can subscribe to at a cost. These register known spammers & IP addresses then flag and 'auto-ban & block' the registration.
