Posting a blacked out screenshot and saying "Ada made me do it" is just weird. You didn't even leave a description. All we see is that you got a DM and there are a bunch of scribbles over it, this is a nothing burger. It being pinned to the top of the community is weird. If you had posted the actual screenshot and made an actual point to what they said and didn't use slurs that insult my child, I'd feel a tad different. But as it stands, this really feels like drama seeking behavior. There is no argument being made, it's just directing people towards Hexbear.
This is the kind of thing that Chapo got banned from Reddit over, the exact event that created Hexbear. If you don't like Hexbear, that's fine. They are generally drama starters, I don't support defederation but I understand why it's being talked about. But you can't call their users slurs, provide no context to what they said, and expect anybody in what is a safe space to be okay with it. It is literally the same thing that makes us discuss defederation with Hexbear, except they don't use slurs.
