I'm new to the fediverse, and so far, I have been seeing some situations from lemmy instances rejecting users to defederating from others, but I ask myself: what can be done if trolls or bots come from self-hosted single-user instances?

Can it be practical if several instances get created programmatically?

Well, if we had a DDOS-like barrage of troll instances, probably a solution would be to institute a "pending federation request" for any new communities.

A reputation/trustworthiness rating for instances might be helpful too, something akin to karma but for the instance as a whole. More vulnerable communities would be able to set a minimum trust requirement for unapproved participation.

I believe there is a whitelist mode, that isn't currently enabled but in that mode new instances are defederated by default. That would be a pain to administer for all the small instances joining, so they may set some size or reputation rules to apply for federation (??). I imagine this is inevitable if automated instance spamming becomes a problem, unless some type of RBL comes in vogue for managing federation first. It may become impossible to manage manually.

E: oh the whitelist thing may only be relevant to kbin federation, as that was the topic I saw it in. Sometimes I forget where I am :-/
