Infrequent posting doesn't necessarily mean dead. Posting a poll and seeing if any feedback came through couldn't have hurt. If you had just gone yourself and made a new community it would have come across different than telling everyone they have to move.

Huh that's a strange reason for a community to switch instances or am I wrong? I feel with Lemmy’s federation, a dead community is by a lack of participation/interest. Its not like another instance will magically have more participation/interest, because we're already federated.
