Social media apps always send push notifications to users to notify them about the activities that are happening in the app. Sometimes, these notifications can be more annoying to the users. If you have signed up on Mastodon, you must be frustrated by the notifications as it notifies when someone mentions you, follows you, follow requests, and more. Fortunately, Mastodon allows users to block notifications (mobile & desktop) based on their preferences.
