For example, a memento (an archived copy) of the web page can be seen at . Note that domain name has changed from to and some extra path segments are added to it.

Fig.1 Link TheFoundingSon Web Cache Fig.2 TheFoundingSon Archived Post In a recent article in Wired, " Yup, the Russian propagandists were blogging lies on Medium too ," Matt Burgess makes reference to three now-suspended Twitter accounts: @TheFoundingSon  ( archived ), @WadeHarriot  ( archived ), and @jenn_abrams  ( archived ), and their activity on the blogging service Medium . Fig.3 TheFoundingSon Suspended Medium Account Burgess reports that these accounts were suspended on Twitter and Medium, and quotes a Medium spokesperson as saying:  With regards to the recent reporting around Russian accounts specifically, we’re paying close attention and working to ensure that our trust and safety processes continue to evolve and identify any accounts that violate our rules.
