Out of the top 15 large and medium-size instances, 3 are currently offline. In the case of lo.t it is only down temporarily for maintenance. However, freak.u has been offline for months and doesn’t show any sign of coming back.
The numbers above are from Fediverse Observer. Numbers of active users do not appear to be reliable for non-Mastodon (i.e. akkoma / plemora / misskey) instances.
Oddballs Online is the most notable new instance with 81 users.
Both Wank Social and rqd2 continue to have solid growth in their userbase.
Cunnyborea Space appears to have disappeared without a trace.
Am I missing any instances with >10 users from the list above? Please let me know by reply or DM.
This list is mainly (although not exclusively) focused on instances that are somehow associated (directly or indirectly) with paraphilias (pedi, hebe, zoo, etc.)
If you find it helpful, let me know!
