The company declined to identify the exact accounts that would be removed by its newly enacted policy, but it did acknowledge that it would "review" accounts and ban groups that identify as extremist through their goals and engage in or promote violence against civilians. This is the result of its enforcement, in other words.

As Gizmodo noted, these extremists are easy targets: they wear their hatred on their sleeve and have few sympathizers outside of their immediate circles. The real test is whether or not Twitter goes after extremists who have relatively wide followings and try to mask their hate with softer language, such as white supremacist Richard Spencer. However, the crackdown suggests that Twitter's enforcement promise isn't just lip service. In theory, it'll spend more time taking action and less time trying to justify inaction.
