Twitter, one of the most widely used social networks, has until now had few ways for reporting harassment and abuse by users. They have recently rolled out new tools in attempt to control vitriolic or abusive messages its members send to each other. The process is not yet automated, so Twitter users still have to report each account that's harassing them. Additionally, Twitter manually reviews each complaint, which also slows the process down, however they are working on improvements. Bystanders are able to report on a user's behalf, and the company plans to improve the speed at which it responds to campaigns. Another new feature includes a more detailed look at users you've asked the service to block, and the company said it plans to add even more tools in the future as well.
