From the official Twitter blog:

Our commitment to move faster to make Twitter safer started in January. First, we conducted research to understand the issues at a deeper level, then we made a range of product updates. We then convened our Trust and Safety Council to gather feedback and help guide us as we move forward.

While there is still much work to be done, people are experiencing significantly less abuse on Twitter today than they were six months ago. What follows is some new data on the progress we’ve made, what we’ve learned, and our plans to continue improving.

Read the blog post for some of the details Twitter offers to back up this claim. Anecdotally, I have noticed a lot less discussion about abuse in my timeline lately. Could just be my particular feed, though. Hopefully, Twitter is on the road to solving this problem.
