@B4ND I know, but I have a habit of going through and clearing/dropping manga that haven't been updated after x amount of time. May take a bit depending on how many titles you have ( I would have almost 800 if I didn't clear!), but I isn't a bad idea to go through your follows list every so often. I generally use the "Dropped" tab for those titles that I will continue to follow, but haven't been updated in a while, while those I decide to completely stop following, I simply put under the "Unfollow". As a note, the reading/dropped tabs on your list actually shows the most recent chapter posted, regardless of language, so you may have titles that show up as recent updates, but in reality haven't been uploaded in your language is quite some time.
