[Suggestion]Chat/Privacy Improvements
If it’s gold sellers you’re concerned about the best thing to do is right click their name and report them for gold selling. That way they’ll get banned. Not right away, but fairly soon. If you report them and block them you don’t need to worry about your block list filling up because you can empty it periodically since all the old ones will be banned already.
I do however agree it would be nice to have more control over who can whisper you. There’s plenty of times someone may not want to get whispers from strangers but also don’t want to block the people who might whisper them (or doesn’t know who they are until it’s too late).
Finally however I should say you don’t need to worry about followers stealing your account info. All that means is they’ve added you to their friends list and you haven’t added them to yours. But they can’t see any more info than they could otherwise. To steal your account they need your email address and password and those aren’t visible to anyone, anywhere in the game for exactly that reason.

I agree with number 1 the most, as I think this is a great solution regarding privacy anyway. Not so sure about 2 or 3, although they have their uses.
As for number 4, I’m pretty sure that gold sellers access your account name and number from the leaderboards available online. Most of the random followers I get are people who have added me after I have helped them in map chat or something, or pugs after a dungeon run.
