Twitter's decision to make an abrupt about-face on blocking policy
after user outcry has highlighted little-understood shortcomings in how social services handle privacy and bullying, sending the 140-character message service back to the drawing board to refine its procedure. Twitter
had thought it was improving the relatively blunt blocking process users were offered when it quietly changed the system on Thursday morning; by the evening, however, the company had been forced to restore the old approach, following criticisms that the amended tools in fact victimized those affected by bullying, rather than the bullies themselves. Meanwhile, the turnaround raises questions around the blocking and privacy tools other popular social networks offer their users.
