Weird way of requesting all events given not all relays support prefixes.
yeah i mean, i don't think it would get all events anyway, so it does just seem like a bad actor.
It's been out there since forever, someone built a very reliable but dumb crawler
i had a feeling ya. at least it seems like its doing something, vs. just blatant trying to cripple the relay like some of the others (repeated reqs to keep the cache blown out)
