You can't use a host alias like that for a site like facebook. That will be resolved to a single IP when the ruleset is created but facebook is actually a vast number of IPs.
You can try to use an AS number either manually:

Or using pfBlocker to auto update it.

Or you could block that using the DNS instead which can be more effective.
