I can’t find any specific Yes / No via search and my understanding is that’s not really possible due to how federated websites work, so hopefully someone more knowledgeable than me can give me a straight answer.
I had something I wanted to post that wasn’t very relevant to any particular community, but more specific to me, kinda like a blog post.
Create your own community where you are the only one able to post. That’s it.
Until now I honestly thought I’d have to host an Instance to create a Community, for some reason. Now I’m a bit embarrassed.
Thank you.
Edit for visibility:
This answer is the direction I chose to go in, mainly for simplicity’s sake.
If the fediverse gods are watching, it might be worth considering automatically making communities associated with people’s usernames. Maybe reserved automatically, but invisible unless you opt-in? That way nobody can create harassment communities targeting your username on your home instance. Just a thought.
Don’t be embarrassed for asking questions and learning something new. No one is born knowing how to self post on Lemmy.
