It's well established that vote anonymity is an important part of representative democracy (discussed elsewhere on this site).
I was listening to the 538 podcast today, and they were discussing phone polling and specifically, how different countries have different measured levels of trust that people are willing to give when a person asks their political opinions and choices on the phone.
At which point, the idea occurred to me - someone can actually figure out who people voted for by using phone polling (either take a legitimate poll's individual level data dump - assuming they are dumb enough to store per-phone call data - or for the slightly more devious, take a phone directory that has names, call people pretending to be doing a legitimate poll, and instead simply record name, # and who they said they voted for/would vote for).
Question: did something like either of those 2 scenarios ever happen (that we know of?)
Related: Do any jurisdictions take steps to protect people's votes from being "outed" by the polls? . Please note that these aren't duplicates - one asks if this actually happened, the other asks if there are steps taken to prevent it from happening, whether it happened or not.
