What have they done wrong? I searched and seems like the previous politic was to simply give the verified status if you reached 100k subscribers without any others verification. How is that verified in any way? Is that verification was merely to state that at least 100k people clicked a button? That would makes it a pretty bad verified status and pretty far from what anyone may expect it to verify. Considering Youtube only remove bots from time to time, it may not even be true. They were never verified in the first place, removing them makes sense.
