I think this is for the best.
I appreciated what you tried initially, because it is important to have external reviews. And I upvoted you. Some of your points were valid and taken into account.
But I have been very unimpressed and disappointed with the way you handled things. Huw summed it well. Your approach was extremely adversarial and you made huge public accusations based on debatable evidence that could have been clarified with a call in many cases.
As such, it became very hard to trust you.
Blaming EA practices, as you are doing, is worrying. It sounds like you are pushing mistakes on others. But getting so many downvotes on the forum is rare. And you wouldn't have gotten them with a different, more measured approach.
Hopefully you learn and improve from the experience.
If I can put this succinctly:
Ironically, in spite of yourself, you probably did have a positive impact, because many of the charities were engaging with you in good faith and took on your feedback. You should be happy mate!
