It’s not about how expected this was. It’s about the fact that we have data to prove it, and it is definitely a probable phenomenon.
Incidentally, I’d be fascinated to see the data the alphabet agencies have doubtlessly gathered on what major players on /r/TheDonald are affiliated with foreign agents (primarily Russia, though China and Israel absolutely had a hand in it too), or just straight up foreign agents themselves. I hear they’re going to release a big report about that on February 31st.
