I have a Twitter account in which I anonymously criticize [more like bad-mouthing than criticizing tbh] Iranian politicians and the Islamic regime. I'd be in jail if I wasn't anonymous. I mostly use TOR browser when I'm doing my illegal online activities [aka saying the truth]. I'm also cautious about what I tweet! I sometimes avoid tweeting/ranting about my ... for example difficult day at work 'cause I fear someone might read it and recognize me. I can go on and talk about other precautionary measures I've taken to stay anonymous but I think you got the idea.
