Twitter settings canÂ mute tweets with specific phrases and keywords.
Although these tweets still will be visible on timeline, they no longer will be included in notifications either through emails, push notifications and text messages/SMS. This is a useful feature to reduce spam and also when being tagged in unrelated tweets.
Here is how to enable this feature in Twitter.com :
Access Settings by clicking the profile photo dropdown menu.
Select Muted words. (Alternatively, go to this link directly : https://twitter.com/settings/muted_keywords after logging in).
Enter the specific keywords and phrases for which tweets are to filtered out. Click Add.
These words/phrases will be listed with status as Muted. To remove them from filter, click on the status and Unmute them.
