As part of the deal, and as a way of involving the sailors, I tell them about the revenue for the project which all comes from the website. The more the website earns the more sailing I can do, the more films they see.
Oh yes, I was also running little blocks of adverts provided by Adsense and, yes, I told my subscribers that I got some money if they visited the websites of those advertisers – all of whom were interested in selling stuff to sailors.
I thought this was not much of a revelation - as any fule kno that is how it works.
I did get the odd subscriber sending me an email saying that he had clicked loads of adverts. This is called demon clicking. I would reply that I would prefer them to only click on adverts they were interested in.
