This is weird. I have made edits with a new account on articles and they were accepted. Not very significant articles, maybe.

It's the same thing with stack overflow/exchange, in which good questions and answers not uncommonly get downvoted and or removed. I think there is an epidemic of petty academic tyrants. These are people who are objectively quite smart but maybe not as accomplished as they wished or hoped so they take out their frustrations on others in the only way they can have control in a world in which they are otherwise irrelevant and powerless. Universities , graduate departments churn out so many students relative to the supply of good paying jobs annually that not everyone will be able to achieve their idealization of career success. What I do know: the TED talk stuff will not work on these people.
