Low quality advice is low quality and there are various ways to determine if an advice is low quality or not, first and foremost is the content of the advice as some mentioned above, then there is how well you relate the point the adviser is making to your own situation, and finally the rank and reputation of the person giving the advice. If they are an expert in their field and have experience in similar situations, then their advice is likely to be more valuable and their rank and merit points will also be higher, which gives them more credibility. If you are being given advice from someone who is not a high ranking member, or even worse is a member with bad reputation, then there is a good chance that their advice will be low quality as well.
