If amateurs and novices of any given subject can use these sites and they are not rude or abusive then why should one be blocked from asking questions. If their questions or responses are poorly worded or irritating in some way should these be censored? Unless every user of these sites has to be eloquent and non-controversial (forgive spelling). If an editor sees a question or response that is irritating or deems it a waste of time indicate it as poorly worded and move on. Do not block the writer from ever asking questions again. How can one learn if one is only allowed a finite number of questions and responses that are poor or irritating?
