This question already has an answer here:
I have a friend who likes to post answers on Stack Overflow. Sometimes he gets overexcited in the rush to post first, and he posts nonsense. When he cools down and looks over his answer he realizes his error and feels a little embarrassed and ashamed. So he deletes his post.
He's concerned that his account might end up being post banned from posting new answers. (as a result of these deleted posts)
What proportion of posts can be deleted before an account runs the risk of being post banned? (my friend is deleting less than 10% of his post)
This isn't a duplicate. The referenced question was asking about deleted questions. I'm asking about deleted answers
