If your post was deleted, you had to get notification about it. Did you got it? If yes, can you show it to us and we wil able to explain what you did wrong. You don't get notification only when whole thread is trashed.
There no quota of deleted posts to ban account. Sometimes even one post is enough to ban user if it was plagiarism or phishing link.
If you don't want to get ban, I recommend to not make low quality posts like this one:
completely agreed.
Also, when you post, try to not repeat what was already said. If you don't have anything to add to discussion, better not post. And avoid posting in spam megathreads.
