I have a Twitter account, and I follow a couple of my friends. When I usually check my Twitter feed, I can see what my friends have posted and reply to it or whatever.
But lately, I've noticed that my Twitter feed is suddenly getting flooded with posts. From people I don't follow or am even interested in following. I'm getting tweets from MTV, ESPN, SportsCenter, Billboard, Imagine Dragons, Justin Bieber, Wiz Khalifa, Perez Hilton, BuzzFeed, the New York Times, and the list just goes on and on. I'm even getting posts from people with 15 followers. Every time I refresh the page, there's about a dozen more new tweets in my Twitter feed.
This has made Twitter completely and utterly unusable for me.
What's going on, and how do I stop it?
EDIT: Strangely, this only happens on the Twitter app on my iPhone; nothing of this sort happens on my computer.
