I have a feeling that this post and your concern is all my fault?

I'm no admin and no mod here but chances are your username is completely fine. Even if it wasn't fine, the admins here wouldn't just ban you without issuing any warnings. I don't think that's very reasonable at least.
My website thing is something more complicated because the staff here has no control over it and they can't simply accept my website's Terms of Service when they are subject to Discord Terms of Service. If my website allows NSFW but Discord doesn't allow it on official servers, then there's very little to discuss. The answer is/will always be "sorry, we can't allow this because Discord may get upset with us if we do".
And my answer to that would be "why don't we just make our own Discord with our own rules" but they didn't even agree on merging their bot with mine so... Lack of trust. Anyway, answering your question, you're probably fine and if I was the reason why you got concerned, I apologize. Wasn't my intention.
Wait for some admin to (most likely) confirm what I said, though. Just to be sure.
