I remember the good old days of Usenet before it was overrun by spam.

Lemmy feels similarly vulnerable because the mods and admins are human, but I feel like we’re flying under the radar only because we’re not big.

I mean sure, the Fediverse has defenses, such as defederation, and networking tools are much better than they were back in those days.

I’m not technical enough to know where the vulnerabilities are, but I still fear that determined, well resourced attackers could still make it unusable.
