VK feed ads are not blocked by NextDNS in Waterfox

Title: Request to review a VK advertising subdomain for possible inclusion in NextDNS blocklists

Hello NextDNS team,

I would like to request a review of the VK subdomain responsible for loading advertisements in the VK web version, particularly sponsored posts displayed directly in the news feed.

My setup uses two independent connections to the same NextDNS configuration:

1. Mullvad VPN: Always enabled, with my NextDNS profile's custom IPv6 address configured as the VPN's custom DNS server.
2. Waterfox: Configured separately to use NextDNS DNS-over-HTTPS through my personal profile: https://dns.nextdns.io/a233a6.

Both connections use the same NextDNS configuration, but through different methods.

The issue:

When uBlock Origin is enabled in Waterfox, advertisements do not appear in the VK news feed.

When I disable uBlock Origin, advertisements appear in the VK news feed, even though Mullvad VPN remains connected, its custom NextDNS IPv6 DNS is enabled, and Waterfox continues using my NextDNS DoH configuration.

I would like to determine which specific VK subdomain is responsible for serving these advertisements.

My request:

Could the NextDNS team investigate the relevant VK advertising subdomain and consider whether it can be added to an appropriate blocklist?

I am specifically requesting a review of the advertising subdomain, not the main vk.com domain. Blocking the entire VK domain would interfere with normal website functionality.

My goal is to block advertisements in the VK news feed using DNS filtering alone, without relying on browser-level ad blockers.

Thank you for your time and consideration.
