What i had to do was pick a social i KNEW they will not like first and get your relationship with them lower...then try the tag face
For example:
Ally-keep on picking Network-BRAG..she'll hate that and after a few (or a lot?) minus points in the relationship, you should be able to Tag Face her
or
Just keep using Tag Face on them..it'll work..just might take a while
