Please have a look at this twitter thread about a dangerous, privacy-abusing app that lets anyone see your public voting history.

A few quotes from his tweet thread:
"It’s currently harvesting my personal contact list and matching it to a voter file (the kind of thing Facebook banned four years ago and Cambridge Analytica did)"
"The data integration on this is impressive. After it downloads my contact list, it finds them on voter files and shows their full vote history."
"When someone who’s in favor of social justice does it, it’s not a privacy violation"
