Twitter's new picture permission policy was aimed at combating online abuse, but US activists and researchers said Friday that far-right backers have employed it to protect themselves from scrutiny and to harass opponents.
Even the social network admitted the rollout of the rules, which say anyone can ask Twitter to take down images of themselves posted without their consent, was marred by malicious reports and its teams' own errors.
It was just the kind of trouble anti-racism advocates worried was coming after the policy was announced this week.
"Anyone with a Twitter account should be reporting doxxing posts from the following accounts," the message said, with a list of dozens of Twitter handles.
Gwen Snyder, an organizer and researcher in Philadelphia, said her account was blocked this week after a report to Twitter about a series of 2019 photos she said showed a local political candidate at a march organized by extreme-right group Proud Boys.
Rather than go through an appeal with Twitter she opted to delete the images and alert others to what was happening.
"Twitter moving to eliminate (my) work from their platform is incredibly dangerous and is going to enable and embolden fascists," she told AFP.
But the rules don't apply to "public figures or individuals when media and accompanying Tweets are shared in the public interest or add value to public discourse."
By Friday, Twitter noted the roll out had been rough: "We became aware of a significant amount of coordinated and malicious reports, and unfortunately, our enforcement teams made several errors."
"We've corrected those errors and are undergoing an internal review to make certain that this policy is used as intended," the firm added.
