An obviously malicious bot like that would be reported and muted by your web of trust, via kind 1984. For something like self-curated feeds, NIP 72 may be suitable
@Hazey Except most clients aren’t using WOT for 1984 events either. My app does, so does Amethyst, but others just ignore 1984 events. And I regularly get called a censor for publishing 1984 events.
