Not worth it.

This isn't useful anymore, there are too many false positives for it to be helpful. You have to go to each account and individually verify whether they were marked as red/green correctly, which defeats the entire point of the extension.

For example, there are many pro-trans advocates and allies are marked red, despite no wrongdoing, by people with personal grudges against them. And there are transphobic people who are marked green purely on the basis of being trans. Who gets marked as red or green isn't supposed to be dictated by one's identity, or by differing opinions on smaller matters within the LGBT+ community (like disagreements over using neopronouns or micro-labels).

The system is supposed to be: red=unsafe (dangerous transphobic accounts), and green=safe (vocal, proactive supporters of trans rights). Because this extension is being misused and poorly moderated, that system doesn't function anymore.

A lot of trans rights supporters, many of whom are trans themselves, are marked red because they talk positively about intersex people, non-binary people (including non-binary transfemmes and transmascs), trans men, or trans people of color. Many Black trans people specifically are reporting that they've been falsely flagged as red because they critique racial disparities within the broader queer and trans communities; this is an unacceptable misuse of the SE extension to isolate or discredit Black transgender people.

I used to rely on SE to quickly block transphobes like TERFs to keep myself safe online, but these days the TERFs are hardly getting flagged as red at all, and too many times I've checked a red account and realized it's just somebody who discussed intersexism, with no evidence to any instances of transphobia in their account history.

This is wrong and demonstrates biases in the team moderating the extension and the dwindling userbase. This needs to be fixed and the rules clarified (and enforced better by the SE curators) to make this extension safe to use again.
