Best way to handle that is not respond if you do not want to help.
Personally, I have tried to help a lot of folks and I have had people help me in other areas.
I know that if I tracked it I have helped a whole bunch more than I have asked for, but, I do not mind helping others out.
I have met some really good folks and I have been burned as well. One guy I helped in later years went and got his NM guiding license and charged other people to hunt spots I showed him. They killed 3 bulls in an area (in less than a square half mile) I brought him into last year, used my butcher shop, my walk in cooler. Needless to say once I found out one of his "friends" was paying him as a guide I called him on it and I will not communicate with him again. What he did was not against the law, but, I considered it chicken sh!t.
I have also met some really good people and their friendship is worth 10x the disappointment I had with my few bad experiences.
My point is, that there are posts like this every year as well. If you do not want to help a newbie then don't. No reason to call them out on it or try to embarrass. If no one helps them their post falls off the edge of the world like all posts do eventually. However, I hope you are being morally honest and not asking others for help in hunting or in other things besides and expecting it.
I have a friend in WY that I am praying will some day draw a tag in NM so I can help him since he generously helped me on 2 antelope hunts and a elk hunt in WY. He has turned into a good friend and I badly want to repay him for what he has done for me and my family. So when someone comes along and needs help in a unit that I am familiar with I have tried to help in most cases.
Sorry for the long post, I just hate to see us look like a bunch of snobs in this forum.
