Just fyi, if you do end up making a discussion post in the agora, you should back up claims you make (about posts that are allowed to stay up on the instances, or conversations with their mods/admins, etc) with screen shots. If I were you, I would also talk to one of the agora mods about whether you should make 1 discussion post, or 2 (1 for each instance you want to defederate from). I’m not sure how they’d want to handle it, but I’m pretty sure it would need 2 vote posts so they may want you to split it.
All the arguments were had here: https://sh.itjust.works/post/11011288
edit: and the subsequent vote where we decided to defederate: https://sh.itjust.works/post/11308397
