After the blackmail and the bullying comes the smear campaign.
How low are you guys going to go with this teenage-like behavior? Is the next step to send guys to beat me up in the car park?
I can very easily demonstrate how wrong your information is since I keep a detailed record of all my lessons activities including footage that I send to my students as part of the lesson service.

The sea breeze arrived at Pinnaroo at exactly 2:40pm that day which is when we began the kite setup.
We launched the kite shortly after 3pm. It was a
steady cross to cross-ON shore breeze blowing at around 12 to 14 knots, perfect for a first land-based lesson and the kite flew really well on short 14m lines.
We flew the kite where the X is marked on the map which is where my permit and the council allow me to operate.
In fact, everyone knows that due to the steep dunes at Pinnaroo it is
simply impossible to fly a kite in that area if the wind is Off-shore, especially on short lines.
Since the student already had prior training we were ready for a practical self-rescue, so he went for a body drag + self-rescue in cross-on shore winds at 3:36pm. Below is a picture of this body drag with the corresponding time stamp and GPS that clearly shows the appropriate wind direction.

And here is the video of the student coming back to the shore from his self-rescue at 3:39pm with the corresponding time stamp/GPS
Now explain how would this even be possible to achieve in off-shore wind?

After the self-rescue we learned the relaunching techniques from the shore.
Shortly after 4pm the wind (which was then southerly i.e Cross-shore) became too light (under 10 knots) so I decided to stop the lesson at the 1h Mark.
The wind stayed southerly for another hour, allowing me to have a quick hydrofoil session before the storm came in shortly after 5pm.
Initially coming from a different school, the student was super stoked about this 1H lesson and has already booked an 8 Hour package. My student's friends and family (some of which kitesurf) were all on the beach watching the lesson and they will all be happy to verify this information.
People aren't stupid, in the long run all these childish attacks end up affecting your credibility and the credibility of the business you work with. Your time is better spent trying to get some customers rather than spying on my activities.
