Holy crap that is a lot of suspicious accounts!
It's impossible to find political conversation on twitter without multiple accounts named like `HouseWifeXX937` (always something with weird characters then numbers at the end) in the middle of the conversations and rarely reply like you would expect a real person to do. Sometimes I wonder if I'm in a conversation entirely with bots and it gets depressing; why would I even want to bother using Twitter beyond talking with people I know are people?
Nowadays I mostly ignore any strangers.
