Important question for relay operators…

The context is a purple pilling event where attendants use wifi. Let’s say 50 of them install nostr clients and suddently start to subscribe all at the same time to various events. This sudden flow of subscriptions would obviously come from the same public IP.

In relay’s context, does this look like a spammy behavior? Could the IP end up being black listed, thus rendering nostr unusable for those newcomers?
