Twitter’s Xiaoyun Zhang shares better news:
You can now export and share your block lists with people in your community facing similar issues or import another user’s list into your own account and block multiple accounts all at once, instead of blocking them individually. We also hope these advanced blocking tools will prove useful to the developer community to further improve users’ experience.
This should make it easier for both users and Twitter to keep tabs on organized groups of abusive and dangerous users. Smart move.
