Finally, a message from Ada:
Hey, sorry about the way this unfolded.
I removed hexbear from the blocklist, as they are defederated from us, and I was unaware that it would mean that hexbear users and blahaj users would be able to interact on 3rd party instances. I'll add them back for now.
Ultimately, the reason I removed them from the list now is that once we have the ability to let users block instances on a per user level, I am open to the idea of refederating with hexbear, because I am aware that many of their trans and gender diverse users want the ability to connect with our trans communities, and trans solidarity is something that I hold to be very important. Enough that I am willing to give this all another go.
However, it was only meant to happen after blahaj users had the option to opt out of interacting with hexbear users, and after I had made an announcement letting people know it was coming. I apologise for the screw up leading to a mini refederation before I gave people a heads up and before the tools were in place to let people choose whether they engage with hexbear users.
