I agree! I started unfollowing people who keeps only making drugwar and actfit posts.
I mean, I think these blockchain apps are cool idea but I don't really want to know what people are doing on them. It's just worse when it is just flooding your feed.
Some of these people I don't want to unfollow since they are still making interesting posts once in a while. So, a way to filter those annoying posts out would be a good idea!
