paul, (edited ) It's Not Safe to Click Links on X Twitter | Lifehacker
Because of the way Twitter link previews works, bad actors are using the user agent to redirect Twitter's link preview bot to a safe URL and human visitors to malicious sites
Note, any website can trick a bot and send a bot one place and users' browsers another place, so this isn't limited to just Twitter. Always trust the site you are going to.
