I'm kind of mixed on this add-on. It is helpful for identifying anti-LGBT news outlets and sites...

But, when it comes to social media accounts, I've encountered accounts that have been falsely mass-reported for seemingly no reason. It's usually pretty accurate, but some accounts seem to be randomly reported. At this point, it's almost more like an indicator on whether someone has ever participated in trans discourse at all rather than an easy yes-trans-safe or no-transphobe system.
