I'm sick of seeing spam threads in forums.
Some of the forums have rules like requiring users have 500 posts before people can create a topic, but it's just a rule to follow and no built in features prevent this from happening. What ends up happening is mods lock those threads, whether they're spam or just people creating threads without the 500 post requirement, but they still pop up, and do frequently.
How about saving mods the trouble, and just have a feature that prevents people from creating new topics on the main boards (i.e. System Wars, Off-Topic, General Game Discussion, Sony, MS, Nintendo, etc) if they don't have the required 500 posts demanded. This should prevent those fake accounts from popping up and spamming with topic creation.
That's probably not a good idea for the game specific forums just because new users might create GS accounts to create topics and ask questions about games. However, this feature should be there for the main forums.
