Whatever your thoughts on the original situation, you know her pronouns now, and you've directly reposted the thing that got you banned. This time around, you don't have an excuse. You know that it's an issue, but you didn't anonymise the post, effectively sharing the misgendering with even more people

I uh, I don’t think it’s reasonable to expect people to check others profiles to ensure we are correctly pronouning them

And yet, in that little whine right there, you managed to use the very gender neutral pronoun that would have saved you all this hassle (including the hassle you're making up of having to go and look up the pronouns of every individual you interact with).

So you know it exists, and you know how to use it, but you decided to try and be funny instead, and it backfired.

You misgendered someone, and now have to deal with the most minor of minorest consequences for harm you caused to another.

You are still free to create 100 different accounts on 100 different instances, just not the one where you broke the rules. No one owes you a platform, deal with it.

Your choice now is to double down and make it worse, or you can be an adult, admit you made a mistake, and learn from it for the future so you don't repeat it.

I dare to say you have already chosen, but feel free to prove me wrong.
