Twitter could have avoided so many problems by sticking to verification as they advertised it - that the blue check mark just meant you were who you said you were and nothing more. It should have provided no benefits other than followers know they're following the right person.
Using it as a stamp of approval is an absolute minefield for a public company. So far the competition is, well, incompetent, but eventually somebody's going to come along and take advantage of these kinds of mistakes.
