I find that Discourse starts automatically blocking CIDR blocks instead of individual IP addresses when it starts seeing a pattern in spammy IP addresses. This results in many genuine users being blocked from using the system. I keep deleting the blocks but they reappear soon after.
Is it possible to stop discourse automatically blocking CIDR blocks?

You can change the `min_ban_entries_for_roll_up` site setting to a much higher value.

Cool thanks, I found it in the Settings → Spam section.
