We should help them if they get in other problem? Like i answered the question in accordance to question which was asked. My answer was also accepted. Now, after some time e.g. hour, day or two. The questioner say that i am now in this issue. Should we help them or they need to add other question for it?
You are in no obligation to listen to them. Politely decline, or don't respond at all. Or tell them to post a new question. Of course, you can help if you want to :)
