Twitter has reversed changes it made to how people block other users, less than a day after they were introduced.

The changes allowed blocked users to continue to see tweets and interact with accounts that had blocked them, leading to an outcry.

Twitter said it was reverting to old rules, under which users are not able to follow an account once blocked.

Blocking is used by people to stop trolls and rude online commentators from interacting with them.

"We have decided to revert the change after receiving feedback from many users - we never want to introduce features at the cost of users feeling less safe," Michael Sippey, Twitter's vice-president of product, said in a blogpost.

"Any blocks you had previously instituted are still in effect."

There have been calls for Twitter to do more to counter cyberbullying following a number of high-profile cases of trolling, where users of the social networking site were bombarded with threats and abuse.

The firm recently introduced a "report Tweet" button to try to combat the problem.
