I try to be a helpful guy, so, when somebody asks me for the name of a good sponsor, registrar or other service, I try to reply with a helpful comment and a link. I include my affiliate code in the link, as it doesn't cost the new affiliate anything, and it can provide an extra few dollars of income for me. Providing details of a good sponsor increases the competition for me, and may result in a reduction of my sales commission, so I think it is fair that I should receive the minimal bonus that one can get from downline sales. So far, not one person has used my affiliate links to sign up despite me replying to requests for sponsors via pm. I'm now considering keeping quiet about monetising names, and just getting on with building sites.
