blocking spotify with pf

[Tim Salvador]

Greetings, 

Recently it has come to our attention that bandwidth has become an issue with increased spotify usage throughout the company. Im looking for a way to block access to it in pf. the rule that i am trying is the following: 

table <spotify> { 78.31.8.0/22, 193.182.8.0/21 } 
block return in quick on $int_if proto tcp from 192.168.1.0/24 to <spotify> port 4070 

For whatever reason it showing that the rule is working but not really working. am i missing something?
