Two highly needed changes in this regard:

1) Include a setting in Character Configuration to let us block Friend requests entirely, so we don't even get them in the first place when we're not expecting one from an actual friend.

2) If we do allow Friend requests to come in, then give us the option of declining the ones we don't want. You already display a "No" button right there on the request. Just make that "No" actually MEAN NO, without all this ridiculous hassle of tracking them down in our Friend list to manually remove them after having already declined their request to be included there.
