I remember that thread, something seemed really fishy to me. Also seems I remember he had not paid back or returned items previously before this thread started. Also, he had no job, was not working and could not help finance most of this himself. Seems like if you want to do a thru hike you should plan and support yourself, not ask for charity. So no, I contributed nothing.
However, I have contributed anonymously to people over the past several years. This has been gear and even cash. My criteria is that they are college kids, they have a job to help support their education, they sound like they will be contributors to our society in the future, AND they DO NOT ask for help. I made one exception to the above rule and donated cash to a couple of hikers last year, who I thought were absolutely outstanding individuals. What I give has no strings attached and no other expectations.
