Not only are these tweets in my Twitter feed eerily similar, they appeared SUCCESSIVELY, from COMPLETELY DIFFERENT SOURCES. What’s happening here?

(REMINDER: I only follow between 5-20 (usually around 10) twitter accounts at any given time, out of over 300 million active users. The statistical probability of these kinds of syncs happening randomly, and on a regular basis like they do, is virtually zero. They are happening on purpose.)
