@lxo Ok, I just caught something. When you've sent your last notice, the answer has not arrived to the remote server; in the logs, I can see that gs.net tries to push your peopletags, but they have no subscribers. Even more, it tries to send them through OStatus, which is not supported neither by Mastodon nor Pleroma.

Could you delete your lists in https://gnusocial.net/lxo/peopletags ? They are easily re-doable if that is not the cause of the issue.
