I think I personally give out more information in what I say than how I vote, and I think that’s going to be true for a lot of people here. I want to share, and that requires me to sacrifice some privacy.
No shade intended, but if you’re concerned about what your voting history will say about you, you might consider not interacting with posts at all, and if you’re really concerned, don’t curate a news feed, either. It’s totally fine to browse logged out if you really want to be safe. I think any level of concern about privacy is valid, but it’s useful to think about the whole picture when you evaluate your risk tolerance.
