Basically Spam Blackhole uses JavaScript to replace a default dummy form submission URL with the true, working form submission link.
Since most spam bots don't execute JS code when parsing a page, they never see the real form submission link.
This way, as the module name hints, spam is sent to a blackhole and never heard from again.
The advantage of Spam Blackhole compared to other similar tools is its extreme lightweight file size and the fact that it doesn't interfere with the page loading time at all, since it doesn't need any big resources loaded on the page to work properly.
