Y U No

Because following a stream makes it show up in your main feed. We want to make sure you only are following the streams you want to follow, fun being the only exception.

Does that mean i can unfollow sports and politics and reactiongifs and those other ones?

Yes you can. Just go to the page of the stream you wish to unfollow and hit the button that says Following. You won’t see any memes from those streams in your feed anymore. They will still be available to submit in from your stream selection, however.

So fun is the only stream you can't follow?
Also I think a lot of people have suggestions for Imgflip but don't know where to put them. If it could be promoted somehow that might help.
