Block Twitter User (Final Step)

The offending person won’t be able to see your tweets on his or her timeline, nor will you be able to see theirs. They also won’t be able to follow you or add your account to their lists. Of course, if your Twitter profile is public, all someone has to do is look up your name and go to your profile to see your tweets, so be sure to lock your account if you want some privacy.
Regret your decision? Just repeat step 1 and click the button that says ‘Blocked,’ and then hit Unblock.

If you just want to stop seeing tweets from particular people but don’t want them to stop receiving your very important tweets, simply Unfollow them. This way you get to keep our follower-to-following ratio respectable.

Just follow these steps:

1. Go to the Twitter user’s profile.

2. Hover over the blue ‘Following’ button.
