I have active notifications from some artists on my Twitter. On my phone, it's always in the notification bar when someone posts something, but it's not unusual for the post to be deleted straight away, even though I can read a snippet of the original text next to the image preview.
Is there any way to locally download/archive every new post from one or more accounts? My PC is on 24/7, so if I need to do something like that, it wouldn't be a problem.
