A very simple anti link-spam thingy.

Browse Source 
I've tried to set it as high as possible without it being uncomfortable. But if text-links seem unresponsive just lower TOPIC_SPAM_DELAY. It's currently set to half a second. That means that a client can only click one link every half-second rather than upwards of 10 a second. So about a 80% reduction.
