Thank you and welcome to GD. The section you have posted in is for
answers to questions. That said it would appear that you have a new question.
Please go here to ask a new question and you can reference this
current question if it is relevant to yours.
That's what I typically use.
Rule of thumb usually if they are a new user they believe the site is treated as a form/board and not a Q&A board. Just be nice, try to show it in your comment, then flag the answer and I or another mod will delete the answer or move it to a comment.
If its an answer of low quality I usually will monitor it, wait for a better answer to be edited but try to encourage a better answer to the new user and if a better answer hasn't been edited within a month we probably will delete the answer. I tend to comment and delete down-voted answers if they hit around -7 but then they will grey out.
Same rule kinda-of applies to a new user that is referencing there site. Encourage a little effort into the community and I believe the community would not be so harsh on votes IF they contribute. Only providing link only answers is poor in quality but we also have to remember that some of us had to learn how SE operates so we must keep that in mind and teach.
