Not OP, but I definitely have -- it's unbelievably annoying to deal with.
I had tweeted something pretty innocuous to a journalist after the election. I wasn't screaming about an illegitimate president or anything of the sort, it was something like, "Maybe we should look at adding more members of congress, it would smooth out the electoral college and make for better representation."
Several months later, some random right-wing asshole with 50,000+ followers retweeted my comment and said something like "Hillary supporters just won't get over losing!"
Within minutes I was absolutely inundated with his moron followers / bots. Literally hundreds of responses calling me a butthurt Liberal and going through my old comments so that I couldn't just block that one.
Twitter was basically unusable for a week afterwards. Can you imagine that shit all the time? None of those people followed me, they knew nothing of me or my politics, they just blindly chase whatever signal their 'leaders' choose to amplify.
