Answer:
Just today, I've had 3 answers deleted, and I've answered 2 or 3 deleted questions. The Brainly staff is who is deleting the posts, because they don't follow the guidelines. The guidelines are pretty much saying you can't post any test questions, anything non-academic, etc. But that's like most of all the posts.
Also, I looked at one of the posts that a deleter person posted, and it was pretty much the answer to an essay. Although it wasn't an actual full-written essay, there were over 5 supporting details in number format (1...2...3...4...).
Not to mention, the answers that were deleted off of my page were all correct, and nothing was wrong with them.
I get that this site shouldn't be for cheating, and I understand that the company could potentially get in big trouble, our answers shouldn't be deleted. I saw one post about depression, it wasn't school related, but it definitely shouldn't be deleted because that person needed help from others. Although this is an academic website, people should be allowed to use it as a way to reach out, and talk to others.
