NextDNS multi-tenant, business firewall usage

Hello,

I manage an array of firewalls for business clients. I presently have an account, @ 350k requests from my home firewall a month, @ 75k requests per month from a firewall I host on DigitalOcean on the same account. These are running pfSense with DNS over TLS, and I have most clients on Cloudflare DNS.

Is it allowed to use this account for multi-tenant purposes, or do you have a tier that would support this service?

Running a DNSBL on a firewall is memory-intensive and may introduce complications. Your solution would be preferable in most of those instances, and I have advocated for NextDNS on various forums.
