SE's inability to protect players from stalking/harassment

[RajNish]

There are just three options that should work as expected. Two-way deletion from friends list. Ignore list, which excludes any possibility of communication, even meeting in dungeon/raid roulettes. And a list of persons who are prohibited from entering your house. The problem would be solved. I do not understand why SE cannot do this when other developers have been using this system quite successfully.
