We is members of SDF, and I don’t really believe that. But even if it were true. If their only merit to creating this instance is to have it be public facing without any of the anti-spam benefits of being SDF-Member only, then it probably isn’t worth it. After all their public Mastodon server mastodon.sdf.org has many upkeep issues and they don’t seem to care much about it. Social.sdf.org is well taken care of, because it’s made specifically for SDF members. This instance should be given the same amount of care and attention that social.sdf.org is but the only way that’s worth it is if they can be sure most people there are validated and trusted members.
