See Katie’s response but blastr is not for (most) private relays. I’m not sure why this is controversial. It defeats the entire purpose.

Ultimately, aggregators have no inherit right to aggregate from ALL relays. Relays maintain the right to determine the rules for interacting with them.
We have IP banned several aggregators from the nostr.wine relays and will continue to do so when they are absurd in their resource usage.
Our goal is to provide value for our paying customers.
