Twitter is quietly hiding accounts behind a warning page - users are baffled

A number of Twitter users are reporting that the site has started hiding their accounts behind a warning message. People visiting their pages are instead being shown a greyed-out version of their profile, with their pictures and tweets hidden from view. A message in the middle of the screen reads, "Caution: This profile may include potentially sensitive content. Do you still want to view it?" Many of the users affected by the barrier appear to be baffled as to why their profiles are being targeted by the site.
