So how can I check my post quality ??
Post quality is subjective. To have high post quality, most of your posts must be relevant to the thread, informative, and contributes to the discussion. Posts that are considered spam are usually very short (but not always), contains nothing meaningful, or repeats what everyone else in the thread has already said.
In order to post with good quality, you must first read the thread you want to post in, then consider whether the post you are making contributes to the discussion. If it does not contribute, don't post. If you are posting for the sake of posting in order to increase your post count, don't post.
