I have been frequently watching the whole threads about this scam since August and just registered, because I could not hold still anymore on my chair!
People, that Bangkok-story is either from a troll or from Trendon/associates... I am 99 % positive (I am a scientist so I will not say 100 %):

• Imagine you had some drinks at a bar. Who the heck writes then in almost perfectly spelled English after some drinks (or did he enjoy only non-alcoholic beers )?
• I do not know, BCB, where you are living, but if you would live at the East coast, Bangkok would be 12 hours ahead, right? There is a gap inbetween the first conversation of 2 hours... pretending you live at the East coast, you messaged that guy after a 2 hour break at around 4:22 AM his time again (it would be even later, if your time was more towards the west coast). Who would come back to you within 40 seconds after you haven´t talked with each other for 2 hours, and that at late night??
• The whole story seems to be a bit too detailed and sry, for my European "taste buds", seems to be a bit too full of cliché Hollywood movie stereotypes. Bank account in Switzerland, then anonymous debit cards worth 1500 Euros each from Poland banks... btw, Poland has still the Zloty, not the Euro. Though I am not sure if Polish banks would sell debit cards in Euros. But if some of you have ever tried to transfer a bunch of dollars from the US to a country in Europe - it is not easy!  
  
• So our Bangkok friend tells on the 25th that he met Trendon "about" three nights ago... BCB then asks him, if he could find out more details. So four days after he met Trendon in the bar, he just goes again into this bar and meets Trendon again? Isn´t that a bit too much of a coincidence? Especially when he says how he probably has to work till 10 PM and then he writes BCB at around 11:28 PM? Seems like he can just walk into the bar and Trendon waits there, ready to give him any information!
• 25th and 26th of October, when the chat between the Bangkok guy and BCB happened... look back in this thread. That was the time, when people tried to find out more about Trendon / tried another enforced effort, to collect information about him. Could it be, that Trendon got cold feet around that time? Oh, must be total coincidence, that the chat happened at this time...  

I know, some of these points above alone are not that much of proof, that it was Trendon or a troll - but all together, it is quite obvious in my opinion!
