As I know inexperience when i see it, and a half assed opinion due to not taking the time, or having the ability to really take in the entire story and put yourself in the shoes of the people involved. If you're going to give advice, try first having experience in the matters instead of opting for the tough love one size fits all approach, and second, have some patience and time to actually read the story, chew it up, and write out a decent reply.
