I answered this question and the OP keeps asking more questions by posting comments on my answer.
Now these extra questions could be answered, but IMO it's starting to get further from the original question. To me, it looks like the OP is asking one question but really is using the 5 Whys technique by using the comment section.
That lowers the quality of the original question and also prevents other members from eventually gaining reputation.
Now, the Help page does have this interesting statement;
Please do not add a comment on your question or on an answer to say "Thank you". Comments are meant for requesting clarification, leaving constructive criticism, or adding relevant but minor additional information – not for socializing. If you want to say "thank you," vote on or accept that person's answer, or simply pay it forward by providing a great answer to someone else's question.
Although it says "requesting clarification" is OK, where do we draw the line between clarifications and asking a new question altogether?
