I'm coming to this specific post late.
But I do wanna say that I've had interactions with the .uk admins over the last year or so. Their user histories exist.
I think it important to note that the individual admins have been public in their support of trans issues. While the slow response is definitely an issue, try not to villainize them without something concrete to back that up. Any of us that disagree with the delay in particular (and please note the inclusive plural), remember that someone can make a bad choice and still be an ally.
Yeah, the optimum response would have been immediate action via comment removals, with debate to follow and reinstatement if merited after debate; combined with prompt communication (within a realistic range of prompt for someone not glued to their instance 24/7). But optimum isn't always going to happen. My grumpy, cantankerous old ass is not often optimum, so I sure can't hold delays and iffy reasoning against anyone else, as long as they get there eventually.
