I don’t see the problem. I don’t have a right to my screen name. Anyone can use variations of that name to post anything they want on any platforms they want. I can’t stop them. And I should not be able to stop them.
If my precious online identity gets hit in the confusion… Well, that’s the risk I take if I have tied my online identity to nothing else but a meaningless pseudonym, easily faked, copied, and impersonated.
For me, this is just a simple demonstration that you can’t trust the name “goat”, and a picture of a goat, as a reliable identifyer. Now that I type it out, this is just stupidly obvious. Anyone who thinks that a goat picture and a nickname reliably identify someone on the internet, is just being very, very stupid in this instance.
I find it dangerous to allow someone to impersonate someone else on the fediverse (an admin too) and begin starting trouble.
I don’t find that dangerous at all. I find it very disturbing that anyone would be stupid enough to believe that the nickname “goat” and a goat picture is enough to reliably identify them as the same person.
All in all, that seems like a non problem to me. A misunderstanding among a stupid minority, easily cleared up, whenever it is desired.
