I think it’s annoying, but im not sure if there’s a clear solution. Id say this type of one sided block is similar to ghost bans and feels just as abusive.

I cant imagine it’s very pleasant on their side either, since it would feel as if everyone from grad or ml were giving you the cold shoulder and make the fediverse feel dead.

The nature of the fediverse is open though - escalating this to another ban/block or banning the custom fork would be counterproductive, imo. If thats their preferred way to curate content, I guess thats their prerogative
