In short, unlike filters and firewalls which handles spam poorly, MB uses machine learning to model the data it collects to identify web traffic spam. If you are interested to see it in action, send me (support@malleablebyte.org) your email and I can send you an invite to try it.
As for the TM, that is what our legal department advice us to do. We are still employees of A*Star so we need to follow their rules. Hope this answers your question.
