It's amazing how people read and hear what they want and do not respond properly to a question or a comment.
To answer your question, I would say I don't know. But I think some people tend to confuse the two. I have no idea how common it is to do so. I would find confusing "infer" and "imply" just about as irksome as not responding properly or in direct enough fashion to a question or a comment.
