Is the number of incidents compared to the number of visitors to Koh Tao enough to refute that it isn't systematic problem?
If the number of visitors is truly enough to refute that there is not a "systematic problem", then why are you so worried about what Ian Yarwood has posted? Obviously his attempt to draw attention to what he and some might consider a problem is not having a material impact on tourism and diving on and around the island? I don't see any concern from the ministry of tourism about Yarwood's posts or articles either, so all must be good on Koh Tao???
And one does not refute things like flat earth, you can't argue with belief...if one chooses to believe the earth is flat despite all evidence to the contrary, any attempt to convince them otherwise is just futile...beliefs are not necessarily fact or science based....religeon is a great example of this....lots of people choose to believe in god, and that their god is the one true god and they will not be convinced otherwise and they will rationalize any smidgen of evidence to justify their beliefs....its not an issue until those folks try to impress their belief on someone with a competing belief or no belief at all.
Yarwood is expressing an opinion. You may not like his opinion, but he not forcing you or anyone else to agree with his opinion. He has pointed to certain incidents to support his opinion and all you have done is complained about what he has expressed. How about presenting some facts to develop a counter point such as the number of tourists that arrive at Koh Tao each week, month, year compared to the actual number of incidents involving tourists resulting in their injury and/or death? How many of them are divers? How about discussing any safety standards imposed by the Thai government or the dive industry in Koh Tao that is designed to increase the safety of the myriad of divers of all ability that choose Koh Tao as their destination? How about something other than complaining about someone's opinion that does not sit warm fuzzy and comfortably with your sense of how things are in that corner of the world.
Whether or not there is a "Sytematic" problem in Koh Toa, there is apparently not a lot of favorable or unfavorable information/news coming from the island...the fact that someone is taking the time to provide any information is a good thing. Just because it does not paint the picture you want to share with the world does not make it wrong or bad, it urges the opportunity for you to paint your own picture of world.
Here are 2 of the many things I have learned in my life so far:
1. The only response to a flood of lies/misinformation is a flood of truth. But the flood of truth must be much greater in quantity and duration than the flood of lies/misinformation to have an impact...Lies only have the burden to create doubt, Truth has the much tougher burden of dispelling that doubt.
2. A captain I worked for during my career in the Navy once said: "The first to the chalkboard wins." What he meant by this is that when developing a plan or expressing an idea the first person/team/etc that presents is typically the plan or idea that will be adopted. People will only tune-in for so long, so if your idea is not the first don't be surprised that someone else's has been adopted. In the case of Koh Tao...neither you nor Koh Tao are doing anything to get ahead of the issues that occur on and around the island. There is no flood of good press. There is just concern about tourism...
...and to that point there are plenty of places in the world other than Koh Tao that are beautiful, have good diving, and will gladly take a diver's money. If Koh Tao is not interested in providing reasons for people to go there, then there either is not a problem or they as a government/institution/etc just don't care.
Again, provide some facts/statistics, spin your story, because continuing to complain is like shouting at the wind.
