Twitter is Now Testing its 'Hide Replies' Option Among Users in Canada

Back in March, Twitter confirmed that it was testing a new option which would enable users to hide selected replies from their tweets, offering a new way for people to control their on-platform experience. As you can see here, the new 'Hide Tweet' option would be added to the tweet drop-down list. When selected, the chosen reply would be hidden not just from your timeline, but from anyone else also - though all users would still be able to choose the 'View Hidden Tweets' option (last frame above) on any tweet to see what the poster has chosen to hide.
