that the only way you are allowed to entice friends with the excitement of flights
So your purpose is clear, you wish to entice friends for excitement! That is precisely what the ANO is trying to prevent. If you advertise a flight within a Flying Club, then there is a fair probability that people who frequent the premises of a flying club will be aware that the level of risk associated with private flying is higher than you might expect on a public transport flight. They can therefore make a reasoned judgement as to whether they travel with you as a passenger or not.
A club may have a website, but your website clearly is not a flying club site.
