Twitter announced a new filter so that users can turn off notification of accounts which does not follow (follow) them. This feature appeared that users could silenceTwitter notifications and garbage cuitan from accounts which have not been verified.
This feature is indeed not sound new. Because, since 2015 Twitter has provided features mute (silence) to keep out the notification from an unknown user account. This time, Twitter update added the ability to use the filter algorithms to identify violent behavior.
All the features to silence an unknown account, new accounts, accounts without a profile picture, your account without the verification email and phone number, to the identification of the cuitan filter to contain violent behavior is now included in the notification options.
To set a filter on the Twitter web browser version, go to the Notification, click settings, and select the check box of the filter options. On iOS and Android, advanced filters can be found in the notification bar under the gear icon.
However, Twitter is still not provide a way to stop mass follow (unfollow) accounts that don't follow back users. Twitter said this to prevent potential abuse of the bulk.
For example, the account owner accidentally posting-follow multiple accounts, thenall of a sudden to unfollow all the account when it was in the follow back. So the account owner can gather lots of follower, following which a bit.
