Make Pi-Hole first time setup more appealing for the masses

This was something you did. Searching the default 7 block lists, this domain is not blocked. It appears to have been included in a block list that you loaded after installation.

If more block lists are added at installation, then more sites are blocked, and user experience suffers. If whitelists are then added, there could be unintended effects.

A recent change in Pi-Hole (V4 I think) was that whitelists for blocklists-serving domains were removed from the software; for that reason.
