I'm not sure if i'm the only one but I recently have been getting different type of notifications that I don't want. the one's the I'm not involved in at all. It's either someone who I follow is now following someone else. someone who I follow is tweeting about this or that. someone I follow has favorite or retweeted this comment. my profile settings were not messed with and have not for a while. I've never gotten these before until recently. not sure what else I need to do?
