I think xenforo must have better privacy settings. There is very general settings now. Sometimes users can argue so they request to block custom members.
Yes xenforo has block feature but it isnt enough when a user block other one, blocked user has continue to like members messages or write to wall.
Usual members request to hide their profiles and messages to search engines but there isnt any settings about that.
I am sure we can raise this requests..
We may create a to do list below this thread..
I hope @Kier @Mike hear us. We really need some enhancement about this.
