If you care about privacy, which I understand, you probably want to leave quickly.
Just because you care about privacy it doesn’t mean that you have to stay indoors all the time. You can still hang around on the town square you just have to be conscious about what you do where.
A big part of caring about privacy is understanding how the platforms you use work and using them accordingly. With proprietary platforms this is often opaque and the rules can change. Open platforms are transparent and you can actually understand them - if you make the effort.
How visible is this to the average user? Just wondering because I have yet to see any spam at all in my Mastodon feeds. Big thanks to the admins for being on top of it!
