I've used this add-on for years. I think it's great in theory. Unfortunately, I have seen a comical amount of Trans people marked red on places like bluesky, because they spoke up about transmedicalism and gatekeeping of nonbinary identities only to have some plugin users coordinate a mass marking that is opposite of their character. I can only assume as a user that the application is now compromised by bad actors. Until this is fixed, my review is: don't use this plugin, it is NOT reliable.
