As some of you might know, I am part of a team of people moderating a Mastodon server. And as so many of those servers we’ve been having some problems with fake signups lately. This is about how we mitigated the issue and how it was beneficial beyond that. So for those who don’t know […]

    Unfortunately Lemmy has one major problem when it comes to banning spam bots. Only the instance that a user belongs to can ban the user in a way that federates to other instances. This means if that particular instance doesn’t quickly ban the user, then hundreds of other instances need to do it manually. Currently, a pretty significant percentage of spammers get banned individually by many instances.

    If we had 100x as many users and 100x as many instances, we would have 100x as many bot accounts for every instance to ban.

    The solution is probably something like shared ban lists or ban mirroring (setting an instance up to ban every user that some trusted instance bans). But right now it’s just people clicking, and it’s not scalable.

      This could be mitigated quite easily by having a clear separation between instances run for users and instances for communities.
