Twitter today introduced new features to enable easier harassment reporting, and improvements to the "block" feature.
From a post on the official Twitter blog today:
Everything that happens in the world, happens on Twitter – to the tune of more than 500 million Tweets every day. That can sometimes include content that violates our rules around harassment and abuse and we want to make it easier to report such content. So, we're improving the reporting process to make it much more mobile-friendly, require less initial information, and, overall, make it simpler to flag Tweets and accounts for review. These enhancements similarly improve the reporting process for those who observe abuse but aren't receiving it directly. And to enable faster response times, we've made the first of several behind-the-scenes improvements to the tools and processes that help us review reported Tweets and accounts.
As for the changes to block, the new blocked accounts page — which you can get to from the settings menu on Twitter.com — shows you the accounts you've blocked. We'll be adding more controls and features to this page in the coming months. Additionally, accounts that you've blocked won't be able to view your profile.
The updates are available now for a small group of users and will be made available to all within the coming weeks.
Starting today we're rolling out an improved way to flag abusive Tweets. See how it works. https://t.co/Yf6cStz0z1
