Ostensibly it is the promotion of the scam, but I don't necessarily buy it. Only a complete retard would fall for this. It makes it look even less legitimate than it already did at first for it to be ultra spammed on every single subforum. Scammers generally try to at least look legitimate, although some target idiots it can't possibly be effective for them to spam every single subforum versus trying to maintain a single post on every subforum.
