What is Global Filter?
If you want to filter out tweets that contain a specific keyword, hashtag, or a username, you can do so with the Global Filter.
This will hide all mentions of this word, hashtag or username from your dashboard (even if you're mentioned in the tweet). The filtered tweets are simply hidden - they are not deleted.
By filtering a word or person, you can also ensure you don't target them in any of your automatic recurring posts. You can addor remove filters at any time.
