How long have you been on twitter? I really don't know but I do know these fake apps will not tell you. While doing my search for scam/spam apps on twitter I ran into the app Time Check Me 2 R spreading the following message:
(Trending Topic) ->I have spent 22.6 hours on Twitter! See how much you have
(Trending Topic) --> I have spent: 35.2 hours on Twitter! See how much you have:
Remember no app can tell you how long you have been on twitter. If your account starts spreading it go into your account settings and remove the app from the list of apps allowed to access your account. If you see anyone spreading this scam make sure you send them a link to this article so they know how to remove it.
