Blosm is a PHP library used for filtering user feedback through a number of antispam filters. One would typically use it to filter blog comment posts, but it can be used for any other similar web forms such as contact-us forms.
It was born out of my desire to filter blog comment posts through both Defensio and Akismet simultaneously, but has been given TypePad support recently. Its main feature is the ability to multiplex many network requests asynchronously so that there is little/no added delay regardless of how many network requests it has to make.
