In the case of Twitter this also permanently broke notifications for my account. It now shows exactly 2 notifications all the time. Both tell me that someone I follow posted a tweet, as if I was too stupid to scroll down the feed myself.

But in return I don't ever get any other notification. The only way to find out whether someone answered my tweet is to manually dig through my own profile.

Needless to say, I don't use Twitter anymore. Because of this, and because 80% of content I saw was just a stream of pure negativity.
