This is a great idea and has my support!
It does make sence, the reason this website has all the sub forums are to PREVENT things like such (the example threads that you put links to) from happening. I also am fed up with spam like that in wrong sections especially from the newcomers, i mean yeah they are new but still.....if your smart youde look arround the website before just posting random junk arround any thread you see ya know?
anyway 10/10 support for this.
