There's no way to do it currently.
I do notice an increase in posts that just advertise a commercial product or announce a game. In order to maintain quality of the site, we need to enforce some policy for which posts are allowed. What I'm thinking of:
For game announcements, the post must contain informative technical details about the development of the game or must be an open-source game.
Advertising commercial non-open-source products is not allowed and will be deleted. Such advertisements must go through the official advertisement channel at DevMaster.
Let me know if anyone has other thoughts on this.
