I was just reading a post about Trump escalating attacks on Bill Clinton.
Yes, you read that right.
Anyway, it had the usual assortment of comments, including one pro Trump comment from someone with what looks like a fake German last name. I checked his profile, and as expected found a mostly empty page. No posts and only one "friend or following". This turned out to be a page for the Chief Executive or Hong Kong, which may not be genuine. All of his posts were in Chinese.
I guess US based trolls are too expensive, so the trolls are coming from a Hong Kong based service, as are the "Make America Great Again" hats.
