The Twitter Timeline Preservation tool is used to automatically take screenshots and transcribe a target’s timeline. Below is a video of the tool in action. After it is done collecting timeline data, it also spits out a current list of who the target is following and who their followers are. Protected accounts are able to be captured as well through user emulation available on the settings tab.
This tool can be particularly useful when developing a social graph of interactions based on retweets, replies, and mentions. Twitter is very flat in terms of providing data weight to relationships. Also, it has very dangerous API sinkholes. Before using this application directly in a Social Graph application, I would recommend reading some of my other pages regarding weighted metrics and sanitizing node boundaries. Best Regards as always!
