Warning sign on the screen " This response is not acceptable.....

and it can not be posted, please don't try again later." Have you seen this warning? I haven't either but how I wish something like this could be done. Just so many irritating postings and responses litter our computer screens. You have just posted a well thought off topic and have done your best to word it in your best possible way and someone just replied and said, "me not" or "I don't know" What can be so irritating? What do you think? I really don't understand why some people do this.
